Abstract

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 (Fermi-statistics) and of the Coulomb and strong interactions of protons in the final state. The distribution of the relative momenta of the protons produced in the charge-exchange process d + p → (pp) + n in the forward direction is found in the framework of the impulse approach. At the momentum transfer close to zero, the differential cross section of the charge-exchange breakup of a fast deuteron on a proton target is determined only by the spin-flip part of the amplitude of the charge transfer reaction n + p → p + n at zero angle. The dependence of the differential cross section of the process d+ p → (pp)+n in the forward direction on the polarization parameters of the deuteron and the proton is investigated. It is shown that the study of the process d + p → (pp) + n with a beam of polarized (aligned) deuterons on a polarized proton target allows one, in principle, 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 on the polarization effects and the spectrum of the relative momenta of two protons produced in forward direction in the charge-exchange breakup of a polarized deuteron on a polarized proton target is investigated. Key-words: deuteron, proton, charge-exchange breakup, spin, polarization, momentum spectrum.
