- The neutron-deficient Ba-119 nucleus has been studied using the Ni-58(Zn-64, 2pn) reaction and the JUROGAM 3 y -ray detector array coupled to the MARA recoil-mass separator setup. One new rotational band and several low-lying states are newly identified. A half-life of T112 = 0.36(2) mu s has been measured for the 5/2(-) bandhead of the nu h(11/2) band. The two previously known rotational bands are confirmed, except for the higher part of the +1/2 signature partner of the positive-parity band. Configurations are assigned based on the analysis of the observed quasiparticle alignments whose nature is unveiled by the calculations using the particle number conserving cranked shell model.
