Lifetimes of excited states in 110Cd have been measured by the Doppler shift attenuation method in the reaction (,2) at =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 =16+, except for the 10+1 state. The structural features are discussed in terms of collective and two quasiparticle excitations.
