Band structures in Rh-99

Excited states in the Rh-99 nucleus were populated using the fusion-evaporation reaction As-75(Si-28,2p2n) at E-lab = 120 MeV and the de-excitations were investigated through in-beam gamma-ray spectroscopic techniques using the INGA spectrometer consisting of 18 clover detectors. The observed band structures are discussed in the framework of tilted axis cranking shell-model calculations. Level structures at low energies are identified as resulting from the rotational bands based on the pi p(1/2) and pi g(9/2) configurations. The Delta I = 1 coupled bands are observed at higher excitation energies and have been interpreted as based on the pi g(9/2) circle times nu g(7/2) circle times nu d(5/2), pi p(1/2) circle times nu h(11/2) circle times nu d(5/2) and pi g(9/2) circle times nu h(11/2) circle times nu g(7/2) configurations. Calculations based on cranked Nilsson- Strutinsky (CNS) formalism have been performed to interpret the favoured states with I-pi = (41/2(-), 43/2(-)) and (51/2(-), 53/2(-)) as maximal spin aligned states built on the valence space nu(d(5/2)g(7/2))(15/2)(3), (17/2)(h(11/2))(11/2)(1) configuration combined with the fully-aligned pi(g(9/2))(25/2)(5) configuration and the pi(g(9/2))(15/2)(5) configuration with one anti-aligned g(9/2) proton, respectively.
