Mixed-symmetry strength in ¹¹⁴Cd

Properties of low-spin states in ¹¹⁴Cd have been studied with the (n,n′γ) reaction, γ-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 2₆⁺ 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.
