Abstract
The exclusive charge exchange reaction at intermediate and high energies is studied within the Bethe-Salpeter formalism. 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.
