Abstract

First calculations based on an impulse-approximation Dirac optical potential are presented. All input parameters are constrained by other experimentally determined quantities. Excellent agreement with $T_{p} = 500$ MeV $p_{pol}$ + ${}^{16}O$ and ${}^{40}{Ca}$ elastic scattering data is demonstrated. The differences between the relativistic and nonrelativistic results are explored in detail.
