Abstract
The nuclear decay of has been studied following the and reactions. Previously unobserved multiquasiparticle states have been identified in with highly K-forbidden decays. One of these, with a half-life of 466±15 μs, is the longest-lived high-seniority (>6) isomer yet discovered. This metastable state offers an opportunity to explore K isomerism as protons are added away from the midshell region. In addition, the excitation energies of several previously “floating” bands have been determined. Energies, lifetimes, configuration assignments, and g factors are discussed and compared to predictions of blocked BCS calculations.
