Abstract
One of the largest sets of collective excitations built on two-quasiparticle configurations in odd-odd nuclei of the proton-rich mass region is reported in . Several new rotational bands and long-lived isomers have been identified. The bandhead of the band is a short-lived isomer with a half-life in the nanosecond range, while the state below it is a long-lived isomer with a half-life of . Two other long-lived isomers have been identified: a 66-keV transition detected at the MARA focal plane depopulates one of them, indicating a half-life in the microsecond range, while no depopulating transitions have been identified for the other, indicating a much longer half-life. Extensive particle number conserving cranked shell model calculations and alignment analysis have been employed to investigate the rich band structure of , which exhibits one of the most complete sets of two-quasiparticle configurations in nuclei close to the proton drip line.
