Differential cross-sections and analysing powers for elastic and inelastic scattering of 30 MeV polarized protons from 112Cd have been measured. The coupled-channel formalism is used to interpret the excitation of the two-phonon states. A good fit to the observed cross-sections and analysing powers for the excitation of the first 2+1 (0.617 MeV) and the second 2+2 (1.31 MeV) states is obtained if the expansions of their wave functions in terms of the one-phonon and two-phonon basis functions are assumed to be orthogonal and if some admixture of the two-phonon component is assumed in the 2+1 state wave function.
