Investigation of $^{110}$Cd with the $(n,n^{\prime}\gamma)$ reaction

Excited states in $^{110}$Cd have been investigated with the $(n,n^{\prime}\gamma)$ reaction using monoenergetic neutrons. Excitation functions, using neutron energies in the range of 2 MeV to 3.4 MeV were collected, and $\gamma$-ray angular distributions at neutron energies of 2.6, 2.9, and 3.4 MeV were performed. The $(n,n^{\prime}\gamma)$ results were complemented with $\gamma\gamma$ coincidences from a $^{110}$In $\beta$-decay experiment (see contribution by A. Diaz Varela) performed at TRIUMF. This has resulted in a comprehensive level scheme for $^{110}$Cd below $\approx 3$ MeV, including stringent limits on unobserved transitions. Level lifetimes were extracted using the Doppler shift attenuation technique. Comparison of the results with simplified model expectations suggests that the low-lying structure of $^{110}$Cd is that of a deformed $\gamma$-soft rotor, rather than a spherical vibrator.
