✦ Synopsis

Using a relativistic nuclear optical potential consisting of a Lorentz scalar, V s , and the time-like component of a four-vector potential, V 0 , with a Gaussian form factor, we have calculated elastic scattering differential cross-sections and polarizations for p + 4 He at intermediate energies for which experimental data are available. We have extended our calculations in order to obtain the differential cross sections for p + 6,8 He elastic scattering at these energies. We compare our results with those of the relativistic impulse approximation (RIA) and with the available experimental data in the range of 0 t 0.22 (GeV/c) 2 .
