Abstract

Properties of low-spin states in ${}^{114}\mathrm{Cd}$ have been studied with the ${(n,n}^{\ensuremath{'}}\ensuremath{\gamma})$ reaction. $\ensuremath{\gamma}$-ray angular distributions and excitation functions have been used to characterize the decays of the excited levels, and level lifetimes have been obtained with the Doppler-shift attenuation method. The one-phonon, mixed-symmetry strength is found to be concentrated in the ${2}_{6}^{+}$ state, which exhibits a strong $M1$ transition to the first-excited ${2}^{+}$ state and a weak $E2$ transition to the ground state. The data agree well with expectations of the neutron-proton interacting boson model.
