Nucleon Exchange in Deuteron Stripping Reactions

Abstract

In the normal theory of stripping reactions it is assumed that the outgoing nucleon comes from the incident deuteron. It is well known that this is not strictly justified (although it may be a good approximation in many cases) because of the need in principle to antisymmetrize the total wave function. This paper discusses the process of stripping with nucleon exchange that appears when the antisymmetry is taken into account. With the help of simplifying assumptions, expressions are obtained for the exchange amplitude in a direct transition between initial and final states of the system. The relation of this treatment to a theory involving compound nucleus formation is discussed.
