Charge-Exchange Reaction pD → n(pp) in the Bethe-Salpeter Approach

The deuteron charge - exchange reaction pD → n(pp) for the low values of momentum transfer and small excitation nergies of final pp - pair is considered in the framework of Bethe - Salpeter approach. The method of calculation of the observables is developed for the case, when the pp - pair is in ¹S₀ - state. The methodical numerical calculations of the differetial cross sections and tensor analysing powers are presented. The reaction under consideration is predicted to be a solid base for construction of the deuteron tensor polarimeter at high energies, and also to obtain some additional information about elementary nucleon - nucleon charge - exchange amplitude.
