Exclusive charge exchange reaction pD --> n (pp) within the Bethe-Salpeter formalism

Kaptari, L. P.; Kämpfer, B.; Semikh, S. S.; Dorkin, S. M.

The exclusive charge exchange reaction pD --> n (pp) at intermediate energies is studied within the Bethe-Salpeter fromalism. The final state interaction in the detected pp pair at nearly zero excitation energy is described by the 1S0 component of the Bethe-Salpeter amplitude. Results of numerical calculations of polarization observables and differential cross section persuade that, as in the non-relativistic case, this reaction (i) can be utilized as a "relativistic deuteron polarimeter" and (ii) delivers further information about the elementary nucleon-nucleon charge exchange amplitude.
