Direct Reactions

Abstract

Direct reactions constitute a powerful tool in the investigation of nuclear properties. However, since for many-nucleon systems even reasonably accurate solutions of the Schrödinger equation, which satisfy the Pauli principle, are very difficult to obtain, analyses of experimental data have commonly been based in a restrictive manner on a variety of phenomenological models for the reaction mechanisms [TO 61, AU 70]. In our opinion, the most serious shortcoming of all these models lies in the fact that one does not know to what extent the requirement of the Pauli principle is satisfied.
