Structure of the high-spin, β -decaying state in the neutron-rich nucleus La146

Excited structures in ¹⁴⁶Ce were populated in β 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, β-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.
