Lifetime spectroscopy of $^{112}$Cd via the $(n,n^{\prime}\gamma)$ reaction

Lifetimes of many levels up to 4 MeV in $^{112}$Cd have been measured using the Doppler shift attenuation technique following neutron inelastic scattering with monoenergetic neutrons. Using these lifetimes, reduced transition matrix elements are determined. The electromagnetic properties of $^{112}$Cd are outlined, and together with results from previous studies, levels are interpreted in terms of single-particle configurations and collective excitations. The separate roles of proton and neutron excitations in a subset of excited states are determined by combining the ground state electromagnetic transition rates with the hadronic transition rates. The collective states and their $\gamma$-ray decays are compared with IBM-2 model calculations that allow for the mixing between the normal phonon states and intruder configurations.
