Abstract
Lifetimes of excited states in ¹¹⁰Cd have been measured by the Doppler shift attenuation method in the reaction ( $\alpha$ ,2 $n\gamma$ ) at $E_{\alpha}$ =25 MeV. Lifetime values for 8 states and lifetime limits for 3 states were obtained. The band structures of ¹¹⁰Cd have been interpreted in terms of a modified version of the interacting boson model (IBM + 2 q.p.). The calculations explain well the excitation energies and electromagnetic transition probabilities up to $J^{\pi}$ =16⁺, except for the 10⁺₁ state. The structural features are discussed in terms of collective and two quasiparticle excitations.
