Abstract
Time-correlated, particle-tagged spectroscopy of the stable nucleus was undertaken with incomplete fusion reactions initiated by beams of and incident on targets of Intrinsic and rotational states above the three-quasiparticle isomer, are reported. The rotational band based on has values that are consistent with the previously suggested configuration assignment. A value of was derived for the collective g factor of which is considerably higher than that found for the ground state. The difference is consistent with a reduction of the proton pairing strength due to blocking in the configuration. A number of five-quasiparticle configurations were identified, the highest of which is an yrast isomer. It decays to an yrast state, which in turn decays to a rotational band based on a state. The state decays to the rotational band associated with Semiempirical calculations reproduce the excitation energies of the three- and five-quasiparticle states above to within The calculations predict that the lowest seven-quasiparticle state will arise from a configuration with which is just beyond the maximum spin accessible with the reactions employed here.
