  In this work we want to study quasielastic (p, n) exchange reactions using a
semi-microscopic optical model derived in a previous work [1] based on a
nuclear matter approach where the real and imaginary parts are given by the
first and second order terms, respectively, of the mass operator obtained by a
Brueckner-Hartree-Fock calculation using a G-matrix built up with an effective
Gogny interaction. The study of these quasielastic reactions is performed
within a Distorted Wave Born Approximation (DWBA) to evaluate the wave
functions in the entrance and exit channels, which in turn are used to compute
the transition matrix elements. This model, which is free of adjustable
parameters, provide a reasonable good agreement with the considered
experimental data, namely differential cross sections, analyzing powers and
total cross sections, of different reactions spanned along the periodic table
at several energies.
