Three-body effects in the (d,He-2) charge-exchange reaction - art. no. 027002

The importance of an explicit treatment of continuum channels in the (d,He- 2) charge-exchange reaction is investigated. The continuum channel effects are clarified by a comparison of the full three-body results with calculati ons which use the distorted waves approximation to the three-body model. Co ntinuum channel effects are shown to reduce the calculated C-12(d,He-2)B-12 (g.s.) differential cross section at 270 MeV incident deuteron energy. This reduction is consistent with that from an earlier ad hoc modification of t he absorptive content of an assumed He-2 optical potential within distorted waves Born approximation calculations.
