A Guide to Authors of Papers in Bulgarian Journal of Physics (BJP-macro package)


Contributions which report significant and original research results in the fields of: General and Mathematical Physics; Particle Physics and Field Theory; Atomic and Molecular Physics; Nuclear Physics; Fundamental Areas of Phenomenology; Theory of Relativity and Astrophysics; Condensed Matter, Statistical Physics; Cross-Disciplinary Physics; and Related Areas of Science and Technology are welcomed.

As a rule, Bulgarian Journal of Physics does not consider for publication short papers of the type of Research Notes, Letters, Communications, etc., and only in exceptional cases the Editorial Board may accept such submissions.

Prospective authors are particularly advised to consult the information accessible via the instruction to authors subpage at the Web, http://www.bjp-bg.com.

Manuscript Submission

Manuscripts may be submitted by a variety of electronic modes (via e-print servers and e-mail: office@bjp-bg.com), or by conventional mail, but not by fax. E-print submission is preferred. Interactive submission forms are an integral part of the submission process for the e-print mode. These forms aid authors in supplying all the information needed in a structured format which ensures efficient processing. Authors submitting via e-mail or conventional mail should download the form available (PDF format) via the author forms subpage, fill it out, and include it with their submission.

Please specify the author to whom correspondence should be addressed, and give all available communications information for this individual (postal and email addresses, phone and fax numbers), since in various circumstances they may all be useful. Please specify the field and give PACS (Physics and Astronomy Classification Scheme®) index categories if possible. The scheme is available at http://publish.aps.org/PACS/.

A copyright-transfer form should be sent as part of your submission, and will be required before publication. While the transfer of copyright takes effect only upon acceptance of the paper for publication in Bulgarian Journal of Physics, supplying the form initially can prevent unnecessary delays. Authors submitting via e-mail or conventional mail can find the form at the last page of the first issue of Bulgarian Journal of Physics of 2005, or on the Web via the author forms subpage; a signed hard copy should be sent to the Editorial Office (we cannot accept forms sent via e-mail).

Normally, manuscripts and figures are not returned to authors. Authors should indicate (preferably on initial submittal) if they want the manuscript and/or figures returned when correspondence is sent during the editorial process, and/or after a final decision has been made.

For detailed information about electronic submissions, see instruction to authors subpage. Properly prepared electronic submissions are exempt from publication charges. Those that use BJP-macro package may qualify for the production program, under which author-supplied files are converted directly to production format and coding, rather than being rekeyed for publication.

Receipt of an electronic submission will be acknowledged by e-mail within 24 hours. Copies of the manuscript should not be sent by conventional mail unless the electronic transmission has not been successful. Figures for an electronic submission must be received in at least review-quality form before editorial processing can begin. The figures may be sent electronically (preferred) while the "originals" are sent by conventional mail as soon as possible.

Manuscripts sent by conventional mail should be submitted in triplicate (original + two identical copies) to

the Editors, Bulgarian Journal of Physics,
5, J. Bourchier Blvd. Sofia 1126, Bulgaria.
The manuscript, including the abstract, references, and captions, should be neatly printed in English, on good letter-size white paper with ample margins. (The first copy, used for production purposes if the paper is accepted for publication, must be printed on one side of the paper only; additional copies, used for review purposes, may be printed on both sides of the paper.) The type size and line spacing should be sufficient to accommodate editorial markings and should be legible to our keyboarders (no more than three lines per inch and no more than 68 characters per line). It should be carefully proofread by the author. Poor reproductions are unacceptable, as are unclear or excessive handwritten insertions.

When a manuscript is resubmitted, please include a summary of changes made and a brief response to all recommendations and criticisms.

The interactive resubmission forms available on our Web page may be used for e-print, e-mail, and hard-copy transmission of modified manuscripts and figures. When resubmitting electronically, send the complete file for the text if there have been any changes. If the resubmission is by conventional mail, send two copies of the revised manuscript (with figures) and include the resubmission form or equivalent information. For any resubmission, please state whether or not the figures have been modified, and supply new PostScript-formatted figures or scanner-reproducible figures if there have been such changes. It is only necessary to resend the "original" figures if the previous versions are no longer valid. Please update any other information (e.g., address and communication information) that has changed or will change since initial submission.

For general format and style consult recent issues of this journal and the BJP style and sample packages at http://www.bjp-bg.com.

Upon acceptance of paper for publication the Authors will be asked for a file with the source code of the paper (with figures' and tables' files), preferably in the BJP or LaTeX format In any case, authors must not use any automatic cross-references between the pages, and should also refrain from automatic cross-referencing the figures and formulae numbers, as well as from creating a bibliography with BIBTEX.

If the files have not been submitted in acceptable electronic format, Authors are expected to pay a publication charge of EUR 10 plus EUR 2 per journal page. In this case a preprint version (in PDF format) of the contribution will be sent to Authors for verification. Acceptable formats are BJP (preferred), LaTeX; PostScript figures. Color-figure and reprint charges are separate from these publication charges and will be specified, and Authors informed, in editorial process.

General Instruction for Manuscript Preparation

Readability of the journal is an important consideration. Authors are urged to take special care in assuring that their manuscripts are well-organized and clearly written in good scientific English.


The title should be concise but informative enough to facilitate information retrieval.


The abstract should be self-contained (no footnotes are allowed). It should be adequate as an index (giving all subjects, major and minor, about which new information is given) and as a summary (giving the conclusions and all results of general interest in the article). It should be about 5% of the length of the article, but less than 500 words.

Sections and Subsections

The {sections} should be numbered with arabic numerals and continued through the whole text in the same fashion (including Conclusions).

Displayed formulae must be clearly typed (written) each on a different line and well-separated from the adjacent text. They should be numbered on the right-hand side either consecutively through the text. Particular care should be taken about the following points:

  • clear distinction between similar letters and symbols;
  • also between (less than) and (bracket);
  • Superscripts and subscripts should be clearly written and properly placed;
  • brackets should be used in the order ;
  • the form exp(...) is often better than e(...) for an exponential. For simple fractions in the text the solidus, , should be used. For example, 12a means 1(2a), not (12)a;
  • in a product that runs on from one line to the next a multiplication sign, , (the same for plus, minus, and equal signs) should be put at the beginning of the second line, not at the end of the first;
  • a zero should always precede a decimal fraction (for example, 0.123);
  • symbols, units, and nomenclature should follow the recommendations provided at http://physicstoday.org/guide/metric.html. Units when specified in formulae, tables and figures should be written in square brackets, e.g., [mm], [GeV], etc.

References to text material must be combined in a single list, numbered consecutively in their order of first appearance in the paper, and placed in a double-spaced list at the end of the text material. They should be designated and cited in text by on-line arabic numerals in square brackets (not with the superscript).

Abbreviations of periodical titles must follow the conventions of {Physics Abstracts}. Whenever possible references to Russian literature should give the original (transliterated; the appropriate table can be found in the Author Index of Physics Abstracts) and a translated version.

For the proper form for references, see the BJP-macro package and recent issues of this journal. The names of all authors of works cited should be given in the references, unless the number of authors is greater than three; in this case, the first author’s name followed by et al. is allowed. When reference is made to internal reports or other items not available in the open literature, it is the responsibility of the author to provide sufficient information to enable the reader to obtain a copy of the referenced material. References to classified reports or other documents with restricted circulation should be avoided. It is important to confirm the accuracy of bibliographic information in references. A work cited anywhere in the paper, including in figure and table captions and in "Note(s) added", should be also included in the reference section.

The list of references is represented at the end of this document.


As an option, footnotes may appear separately from references and be placed at the bottom of the page on which they are cited. They should be designated by superscript numbers and numbered consecutively throughout the paper. Footnotes within tables should be designated by lower-case letter superscripts and given at the end of the table.

All information concerning research support should appear in the acknowledgments. Footnotes which describe an author’s position or title are not acceptable.


Separate tables (numbered in the order of their first appearance) should be used for all but the simplest tabular material; they must have captions, which should make the tables intelligible without reference to the text. The structure should be clear, with simple column headings giving all units. Each table must have a caption that makes it intelligible without reference to the text; list captions on a separate sheet.


Illustrations and figures should be planned for the column width (11.2 cm) of the journal. Authors are encouraged to submit all figures electronically, even if the text of the manuscript is not submitted electronically. Figures submitted on paper should be of high quality and suitable for digital scanning, which is done at 600 or 1200 dpi depending on the level of detail; original ink drawings or glossy prints are acceptable. Be advised that the scanner reproduces all imperfections (e.g., correction fluid, tape, smudges, writing on the back of the figure, etc.). The symbol width and lettering height on the journal page should be at least 2 mm. The resolution of the drawing software and output device should be set as high as possible (preferably 600 dpi or higher). Figures should be numbered in the order in which they are referred to in the text. An indication, e.g., "TOP", of the intended orientation of a figure is helpful, especially in ambiguous cases. Each figure must have a caption that makes the figure intelligible without reference to the text; list captions on a separate sheet. Groups of figures that share a (single) caption must be labeled "(a), (b)", etc. The figure itself should have properly labeled axes with correctly abbreviated units enclosed in parentheses. Use consistent lettering and style as in the body of the text. Avoid submitting prescreened prints of photographic material or laser-printed renditions of continuous-tone data; reproduction of such figures is seldom satisfactory in the final product. If PostScript files are not available, supply glossy or matte-finish photographs or laser prints at the highest resolution possible and in the final published size.

Some figures might be more effective in color. The cost of printing illustrations in color, which may be significant, must be borne in full by the respective authors and their institutions. If color is desired in the print version of the journal, the author must indicate acceptance of the applicable charges. Pricing information may also be found from this site. The form may be completed as part of the submission process. It must be completed before production can begin on an editorially accepted paper that contains color for the print journal.

If figures are reproduced from other articles the source must be quoted, and the permission for reproduction obtained by the Authors from the owner of the copyrights must accompany such materials.


Proofs should be checked carefully and returned promptly. Only essential corrections should be made and alterations involving displacement of type should be avoided. The name of the author to whom proofs are to be sent should be indicated in the covering letter.
