Dirac optical potentials constrained by a Dirac-Hartree approach to nuclear structure

Lorentz scalar and four-vector optical potentials are obtained for protons elastically scattered from ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$, ${}_{}{}^{40}{}_{}{}^{}\mathrm{Ca}$, ${}_{}{}^{48}{}_{}{}^{}\mathrm{Ca}$, ${}_{}{}^{90}{}_{}{}^{}\mathrm{Zr}$, and ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$. It is demonstrated that Dirac optical potentials constrained by relativistic Hartree theory are capable of producing good agreement with experiment.
