Abstract
The lifetimes of several states in 110Cd have been determined by means of the generalized centroid-shift method. The reaction 108Pd($\alpha$,2n) has been used and the following results were obtained: T1/2(2879 keV) = 0.60 $\pm$ 0.10 ns, T1/2(3029 keV) = 0.30 $\pm$ 0.10 ns, T1/2(3056 keV) = 2.25 $\pm$ 0.10 ns, T1/2(3611 keV) = 0.45 $\pm$ 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 $\nu$(h11/2d5/2) has been established with the band-head at J$^{\pi}$ = 7-2 identified as a new two-quasiparticle isomer, the lower-lying 5-1,2 states being of two-quasiproton character.
