Abstract. Wigner R-matrix expressions for neutron resonance cross sections are transformed into the ratios of meromorphic functions of energy. A computer code REFINE has been developed to convert the resonance parameters of ENDF/B-6 into the parameters of our method. The results for resolved resonances of 239Pu are presented as an example.
