Configuration Mixing Effects in Stripping

The bound "single-particle wave function" into which the stripped particle is inserted is a true single-particle wave function, in the shell-model sense, only if the target nucleus is a closed-shell nucleus. In all other cases the radial shape of this function is altered by configuration mixing effects, and important changes of cross-section magnitudes may ensue. These effects are discussed in the present article, and a detailed comparison is given with the customary phenomenological procedure wherein the configuration mixing effects are estimated in terms of the $Q$ of the reaction.
