Abstract
The decay of has been studied resulting in the first detailed information on the excited states of . About 25 levels were found, of which two were γ-decaying isomers. The expected low-lying quadrupole vibrational levels could not be identified. The observed decay rates for β and γ transitions have enabled the classification of some levels, including the β-decaying ground state of , in terms of specific two-quasiparticle states. The total beta-decay energy of was obtained as 5.155(35) MeV.
