Deuteron Stripping on a Realistic Nucleus

Abstract

A model for deuteron stripping is formally examined in which both neutron and proton can excite collective degrees of freedom of the target nucleus. A set of coupled equations is derived and truncated by defining optical-model potentials. Appropriate optical-model potentials for computing are discussed and compared with potentials for related reactions such as proton elastic scattering. An expression for the stripping amplitude is derived in the weak-coupling limit. It describes all possible excitations in the model, not just the single-particle component of the final state as current stripping theory does. The purpose of the paper is to show what is involved in obtaining a realistic description of stripping and to make the approximations as explicit as possible.
