Abstract
Excited states in with spins up to were investigated in two separate experiments using reactions at beam energies of 12.5 and 14.5 MeV. Two- and threefold -ray coincidence data were collected using the CAESAR and CAGRA spectrometers, respectively, each composed of Compton-suppressed high-purity germanium detectors. Analysis of the data revealed rotational bands built on several two-quasiparticle intrinsic states, including a long-lived isomer. Configuration assignments were supported by an analysis of in-band properties, such as values. The excitation energies of the observed intrinsic states were compared with results from multi-quasiparticle blocking calculations, based on the Lipkin-Nogami pairing approach, that included contributions from the residual proton-neutron interactions.
