Elastic and inelastic observables for the scattering of 500 MeV protons from {sup 40}Ca 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 Schroedinger coupled channel programs. The relativistic approach reproduces the inelastic observables better than the first-order nonrelativistic impulse approximation model.
