Spin excitations in the $^{40}Ca(\vec{p},\vec{p'})$ reaction revisited

Abstract : 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. (APS)
