Collective excitations in 106Cd

High spin states in 106Cd were populated by the reactions 94Zr(17O, 5n) and 76Ge(34S, 4n) at 80 MeV and at 148 MeV, respectively. The γ-decay was studied by γ-spectroscopic methods using the Nordball multi-detector array. Protons and α-particles were detected in particle detector system, thus selecting the neutron channel. The experiment included γ-ray yields, γγ-coincidences and γ-ray angular correlation measurements. Collective bands extending up to spin 26++, 20− and 21 −, have been observed in 106Cd. A new lifetime of 11+6-3, ns for the 16+ state at 7118.7 keV has been found. Both total Routhian surfaces and spin diabatic surfaces have been calculated and used for assigning quasiparticle configurations to the bands. The (+, 0) band is assigned as a vh2112 configuration below I = 16+ and at higher spins suggested to be built on a πg292vh2112 configuration. The large hindrance observed for the decay from the 16+ state supports the latter assignment. With the alignment of the vh2112 pair the deformation is predicted to change from (ϵ2γ) = (0.13,-2°) to (0.17,4°). The configuration of the negative parity bands is assigned as either a vh1112d152 or a vh1112(g72⊗d52)1, with (ϵ2,γ) = (0.14,9°).
