ELSEVIER Nuclear Physics A586 (1995) 351-376 High-spin proton and neutron intruder configurations in 1°6Cd

High-spin states in l°6Cd have been studied with the reactions 94Zr(160, 4n)l°6Cd and 76Ge(348, 4n)l°6Cd. A rotational band, based on a two-quasineutron (hll/2)2 configuration, is observed from its 10 + bandhead to spin 28 h. This structure undergoes a band-crossing at a rotational frequency of approximately 0.45 MeV/h, interpreted as the alignment of a pair of g7/2 neutrons. Time-correlated spectroscopy has been used to identify states above the previously observed 12 + isomer at 4660 keV. These include a weakly populated, strongly coupled structure which indirectly feeds the isomer, and whose alignment and in-band decay properties are consistent with a deformed v(hll/2)27r(gg/2g7/2), four-quasiparticle configuration. The results are discussed in terms of cranked-shell-model and total-routhian-surface calculations. No evidence is found for a reported 16 + isomer at 7119 keV
