The high-energy approximation is adapted for heavy ion scattering at energi
es of several dozen MeV/nucleon. It is shown that the closed form of the ei
konal phase suggested for the realistic Woods-Saxon type potential is a hop
eful one for further applications. The Glauber-Sitenko small angle approach
is analyzed, and a role of the Coulomb deviation of the straight trajector
y of motion is investigated. Methodical calculations and comparison with ex
perimental data are made.
