Identification of excited states in 119Ba -: art. no. 044329

Excited states have been identified in the very neutron-deficient Ba-119 nucleus. Two bands have been observed, which are likely to be based on h(11/2) and (g(7/2)d(5/2)) neutron orbitals. Despite this being the first observation of excited states in Ba-119, the bands extend to (75/2)(h) over bar and (79/2)(h) over bar, respectively. The bands have been assigned to Ba-119 using gamma-recoil and gamma-x-ray coincidences. Several quasiparticle alignments have been identified. involving neutron (h(11/2))(2) and proton (h(11/2))(2) aligned configurations. Furthermore, the bands show features which are reasonably consistent with smooth band termination at high spin. Theoretical results for Ba-119 are discussed within the framework of cranked Woods-Saxon and Nilsson-Strutinsky calculations.
