N2 - The properties of 2+ states at 2156 keV and 2231 keV in 112Cd have been measured using the (n,n ′ γ) reaction. These states have strong decay branches, determined to be almost pure M1, to the 21++* level with B(M1) values of 0.044(5) μ2N and 0.055(5) μ2N respectively, and are interpreted as the main fragments of the 2+ mixed-symmetry state, the vibrational analogue of the "scissors-mode" state in deformed nuclei. These observations provide the first firm evidence of mixed-symmetry states in a good U(5) nucleus.
