Resumen
Full-folding model calculations of proton elastic scattering at intermediate energy made using the
free off-shell NNt matrix and including the variation of the energy in the NN center of mass as
prescribed by the full-folding model are compared with similar calculations using t matrices evaluated
at a fixed energy. The fixed energy is chosen on the basis of the incident beam energy ignoring
the Fermi momentum of the struck target nucleon. Near 200 MeV, the energy prescription for the
NNt matrix is found to be responsible for much of the difference between recently reported fullfolding
calculations as well as for the differences between full-folding calculations and conventional
tp approximations to them. The sensitivity of the scattering observables to the starting energy suggests
that at lower intermediate energies, explicit medium corrections should be included in applications
of the full-folding model.
