Spin effects and relative momentum spectrum of two protons in deuteron charge-exchange breakup

The relation between the differential cross section of the charge-exchange breakup of a fast deuteron d+p -> (pp)+n and the differential cross section of the charge transfer process n+p -> p+n is discussed taking into account the effects of the proton identity and of the Coulomb and strong interactions of protons in the final state. The distribution of the relative momenta of the protons is found in the framework of the impulse approach. It is shown that the use of polarized initial deuterons and protons allows one to separate two spin-dependent terms in the amplitude of the charge transfer reaction n+p -> p+n at zero angle and to determine their phase difference. The influence of the deuteron d-wave state is investigated.
