Abstract. This contribution presents nuclear structure data on 105Ru, produced via the 104Ru(d,pγ)105>Ru reaction. Excited states with energies up to 1.05 MeV have been studied. The γ-rays were detected by using ROSPHERE – the ROmanian array for SPectroscopy in HEavy ion REactions, in a mixed configuration consisting of 14 HPGe detectors and 11 LaBr_3:Ce scintillators. The (d,pγ) reaction populates predominantly low-spin states which can also be populated in the n-capture on 104Ru. For the first time, γ rays emitted after the (d,p) 105Ru reaction are observed. 105Ru is interpreted as a triaxial nucleus and its excited states are analyzed by using the Triaxial Rotor plus Particle Model.
