Spin excitations in the ⁴⁰Ca(p^→,p^→′) reaction revisited

Double differential cross sections d2σ/dωdΩ and spin-flip probabilities Snn have been measured for the 40Ca(p→,p→′) reaction at Ep=319 MeV. The angular range of the experiment was 10.5°≤θlab≤23° and the range of excitation energies was 6≤ω≤47 MeV. These data and earlier data at smaller angles are compared to calculations employing random phase approximation nuclear structure and a distorted wave impulse approximation reaction model.
