Structure of the high-spin, -decaying state in the neutron-rich nucleus 146La

Excited structures in 146Ce were populated in beta decay of the high -spin state in the neutron -rich nucleus 146La. The beam was produced by the Californium Rare Isotope Breeder Upgrade (CARIBU) facility at Argonne National Laboratory, reaccelerated by the ATLAS accelerator, and implanted on a moving -tape system in the middle of the GAMMASPHERE array. The decay scheme of the high -spin, beta-decaying state in 146La was revised with respect to previous studies and evaluated nuclear data. The structure of 146La is discussed in the framework of the deformed Nilsson model and systematics of known quasiparticle structures in the region.
