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: T_1/2(2879 keV) = 0.60 $\pm$ 0.10 ns, T_1/2(3029 keV) = 0.30 $\pm$ 0.10 ns, T_1/2(3056 keV) = 2.25 $\pm$ 0.10 ns, T_1/2(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 $\nu$ (h_11/2d_5/2) 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.
