Abstract
High-spin states in Cd106 have been studied with the reactions Zr-94(O -16, 4n)106Cd and Ge-76(S-34, 4n)106Cd. A rotational band, based on a two-quasineutron (h11/2)2 configuration, is observed from its 10+ band head to spin 28 HBAR. This structure undergoes a band-crossing at a ro tational frequency of approximately 0.45 MeV/HBAR, 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 struc ture which indirectly feeds the isomer, and whose alignment and in-ban d decay properties are consistent with a deformed v(h11/2)2pi(g9/2g7/2 ), four-quasiparticle configuration. The results are discussed in term s of cranked-shell-model and total-routhian-surface calculations. No e vidence is found for a reported 16+ isomer at 7119 keV.
