Surface response model results for quasielastic nucleon-nucleus scattering are compared to recent intermediate energy (p,p’) spectra. The energy and target dependences of the quasielastic peak, as well as the dependence on momentum transfer, are quite accurately described by this model. Discrepancies at large energy and momentum transfers are ascribed to multistep processes, and they become more significant at lower beam energies. Shell structures of finite nuclei, which are not contained in the model, are the main source of the discrepancies at small momentum transfers.
