Decay of 1.643-hr Ru-95 to Tc-95

The decay of Ru-95 has been investigated by means of gamma -ray spectroscop y.. The Ru-95 nuclei were produced by the reaction Mo-92(alpha ,n)Ru-95 at the beam energy of 17 MeV. High-purity Ge detectors have been used singly a nd in coincidence to study gamma -rays In the decay uf Ru-95 to Tc-95. 132 gamma -rays are reported. among them, energies and intensities Fur 127 tran sitions have been determined. A decay scheme of Ru-95 with 31 levels is pro posed which accommodates 127 of these transitions. Spins and parities for t hree new levels are proposed from calculated logft values. measured gamma - ray branching ratios. and in-beam experiment results of the daughter nucleu s Tc-95.
