The angular distribution of protons from the reaction /sup 28/Si(n,p)/ sup 28/Al induced by 14.1 Mev neutrons and leaving the nucleus /sup 28/Al in the ground or in the first excited state has been calculated in the distorted wave Born approximation assuming a finite range effective n-p interaction. Some of the calculated curves are reported; they display the relevance of a Majorana exchange term in the effective interaction and of the optical model distortions in the initial and in the final state for obtaining a reasonable agreement with the experimental data. It is found that, in order to get from the theory the measured absolute value of the cross section, with the optical model distortions fitting the elastic scattering data, the effective irteraction must be normalized in strength to the t-matrix describing nucleon-nucleon scattering in nuclear matter, with binding effects included.
