“…In recent years, some major advancements in the spectroscopic techniques has made it feasible to populate the high-spin band structures in atomic nuclei to the extremes of angular-momentum, excitation energy and isospin [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. In some nuclei, the high-spin states have been studied up to angular momentum, I ≈ 60h and as many as twenty side bands have been identified [9][10][11][12]14]. The observation of these rich band structures poses a tremendous challenge to theoretical models to elucidate the properties of these structures.…”

In an effort to elucidate the rich band structures observed in odd-neutron systems, triaxial projected shell model approach is extended to include three-quasineutron and five-quasiparticle configurations. This extension makes it possible to investigate the high-spin states up to and including the second band crossing. Detailed investigation has been performed for odd-mass Xe isotopes with the extended basis, and it is shown that character of the band crossing along the yrast line changes with shell filling of the 1h 11/2 orbital. Further, it is observed that the three-quasiparticle state that crosses the ground-state configuration, leading to the normal band crossing phenomenon along the yrast line, first crosses the γ band based on the ground-state configuration at an earlier spin value. This crossing feature explains the occurrence of the signature inversion observed in the γ bands for some of the studied isotopes.

An experiment involving a heavy-ion induced fusion-evaporation reaction was carried out where high-spin states of 123 Xe were populated in the 80 Se(48 Ca, 5n) 123 Xe reaction at 207 MeV beam energy. Gamma-ray coincidence events were recorded with the Gammmasphere Ge detector array. The previously known level scheme was confirmed and enhanced with the addition of five new band structures and several inter-band transitions. Cranked Nilsson-Strutinsky (CNS) calculations were performed and compared with the experimental results in order to assign configurations to the bands.

High-spin states in 123 Xe were populated in the 80 Se( 48 Ca, 5n) 123 Xe reaction at a beam energy of 207 MeV. Gamma-ray coincidence events were recorded with the Gammasphere spectrometer. Four new high-spin bands have been discovered in this nucleus.The bands are compared with those calculated within the framework of cranked Nilsson-Strutinsky and cranked Nilsson-Strutinsky-Bogoliubov models. It is concluded that the configurations of the bands involve two-proton excitations across the Z = 50 as well as excitation of neutrons across the N = 82 shell gaps resulting in a large deformation, ε2 ∼ 0.30 and γ ∼ 5 • .
