Abstract

Excited structures in ¹⁰⁴Mo were populated by β decays of the ground and isomeric states in the neutron-rich nucleus ¹⁰⁴Nb. The beams were produced by the CARIBU facility at Argonne National Laboratory, re-accelerated by the ATLAS accelerator and implanted on a moving-tape system in the middle of the GAMMASPHERE array. Separate decay schemes for the two β-decaying states in ¹⁰⁴Nb were constructed for the first time. The structure of the isomers are discussed in the framework of the deformed Nilsson model and systematics of known quasiparticle structures in neighboring nuclei.
