Inclusive d charge exchange and breakup

The reactions -d'0X and +d'+X are calculated within a relativistic three-body model and compared with recent data at 164.1 and 96.5 MeV, respectively. Contrary to expectations based on the impulse approximation, the differential cross sections of both reactions exhibit a strong suppression in the forward direction. It is shown that this suppression is due in the first case to the action of the Pauli principle on the two final neutrons, and in the second case to the orthogonality between the initial deuteron and final neutron-proton wave functions. The results of the full model agree well with the available differential cross sections at the two energies.
