Three-Body Breakup; Deuteron Dissociation Cross Sections

An analysis of the reaction $X(d, np)$ has been carried out within the framework of the algebraic theory of scattering. It is possible to cast the transition matrix element governing the process into several forms. In particular, one of these, the asymmetric form, involves no nuclear interactions for one of the deuteron constituents. The other forms, so-called symmetric, contain interactions for all particle pairs and are shown to be inherently superior to the asymmetric expression.
