Abstract

Level energies in two-quasiparticle (2qp) structures in 156 61Pm95 are evaluated using the phenomenological rotor-particle model for odd-odd deformed nuclei with the inclusion of the residual p-n interaction contribution. Using these results as location guides, the experimental data from a recent 156Nd decay study are used to construct a level scheme for 156Pm with excitation energies upto 550 keV, wherein 26 (out of 30) γ’s reported in 156Nd decay are incorporated. Spin-parities and configuration assignments are suggested for 15 levels, in addition to the two isomers, in this energy domain. These investigations point to the need for information on higher-energy γ’s and on β-γ and γ-γ coincidence data from 156Nd β-decay to confirm these assignments.
