Structure of the high-spin, $\beta$-decaying state in the neutron-rich nucleus ${}_{146}\mathrm{La}$

Excited structures in ${}_{146}\mathrm{Ce}$ were populated in $\beta$ decay of the high-spin state in the neutron-rich nucleus ${}_{146}\mathrm{La}$. 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 ${}_{146}\mathrm{La}$ was revised with respect to previous studies and evaluated nuclear data. The structure of ${}_{146}\mathrm{La}$ is discussed in the framework of the deformed Nilsson model and systematics of known quasiparticle structures in the region.
