Comparison of relativistic and nonrelativistic approaches to the collective model treatment of p+40Ca inelastic scattering

Elastic and inelastic observables for the scattering of 500 MeV protons from Ca40 are calculated using either the first-order relativistic or nonrelativistic impulse approximation for the diagonal potentials and a collective model for the transition potentials. The calculations are done using either Dirac or Schrödinger coupled channel programs. The relativistic approach reproduces the inelastic observables better than the first-order nonrelativistic impulse approximation model. © 1990 The American Physical Society.
