Abstract

Four highly deformed structures in the odd-odd nucleus Pm-136(61)75 were observed via the Pd-105(Cl-35,2p2n) reaction at 180 and 173 MeV using the GAMMASPHERE gamma-ray spectrometer and the Microball charged-particle detector array. Quadrupole moment measurements were performed on all of the bands. In contrast to lighter odd-Z Pm and Pr nuclei, bands based on the g(9/2)[404]9/2 proton orbital were not observed. Instead, the four observed sequences are assigned as a coupling Df an i(13/2) neutron with the low-Omega h(11/2) and mixed d(5/2)g(7/2) orbitals. Comparisons with neighboring highly deformed structures are discussed and cranked Nilsson-Strutinsky calculations for Pm-136 are presented.
