Highly deformed band structures due to core excitations in ¹²³Xe
Abstract
High-spin states in ¹²³Xe were populated in the 80Se(48Ca, 5n)¹²³Xe reaction at a beam energy of 207 MeV. g-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, e2≈0.30 and g≈5°.
