Abstract:

The lifetimes of several states in 110Cd have been determined by means of the generalized centroid-shift method. The reaction 108Pd(α,2n) has been used and the following results were obtained: T1/2(2879 keV) = 0.60 ± 0.10 ns, T1/2(3029 keV) = 0.30 ± 0.10 ns, T1/2(3056 keV) = 2.25 ± 0.10 ns, T1/2(3611 keV) = 0.45 ± 0.10 ns. Electric dipole and quadrupole transitions are discussed in terms of octupole and quadrupole collectivity. The odd-spin sequence of the semi-aligned structure ν(h11/2d5/2) has been established with the band-head at Jπ= 72 identified as a new two-quasiparticle isomer, the lower-lying 51,2 states being of two-quasiproton character. Nuclear Reaction:108Pd(α,2n), E = 27 MeV; measured Eγ, Iγ, γ-r.f. Deduced: T1/2, B(αL) in 110Cd. Ge detectors. Generalized centroid-shift analysis.
