Isobaric-analog-state transitions in the (p,n) reaction at 135 MeV and density-dependent impulse-approximation calculations.

We compare density-dependent distorted-wave impulse-approximation (DD-DWIA) calculations with experimental ({ital p},{ital n}) cross-section angular distributions at 135 MeV for ten nuclei from {ital A}=14 to 208. The DD-DWIA calculations use a {ital G}-matrix interaction based on the Bonn one-boson-exchange potential and empirical optical-model parameters. The agreement between the calculations and the experimental results is excellent with normalization factors required that are within 10% of unity; these factors are within the experimental scale uncertainties.
