Abstract：
The Lorentz invariant relativistic optical potential has been discussed at energies below 300 MeV. The Dirac equation with scalar and vector potentials is exactly solved by the partial wave method. The calculated results of proton-⁴⁰Ca in the energy region 300-65 MeV are presented and compared with the experimental data of the differential cross section dσ/dΩ analyzing power A_y(θ) and spin rotation function Q(θ). It can be shown that the improved relativistic optical potential fits data well.
