Query: One-particle exchange in the double folded potential in a semiclassical
  approximation   The one-particle exchange in the double folded model is analyzed. To this aim
the Extended Thomas-Fermi approach to the one-body density matrix is used. The
nucleon- nucleon force with Yukawa, Gauss and Coulomb-type form factors are
considered. The energy dependence of the exchange part of the double folded
potential is investigated and a comparison of the present approach with former
ones is carried out.
