Query: $p+^{4,6,8}He elastic scattering at intermediate energies   Using a relativistic nuclear optical potential consisting of a Lorentz
scalar, $V_{s}$, and the time-like component of a four-vector potential,
$V_{0}$, we calculate elastic scattering differential cross sections and
polarizations for $p+^{4}$He at intermediate energies for which experimental
data are available. We also calculate the differential cross sections and
analyzing powers for $p+^{6,8}$He at intermediate energies and compare with the
few available experimental data.
