Cross section and deuteron analysing powers of the 1H(d, 2p)n reaction at 200 and 350 MeV

Abstract

The cross section and analysing powers A y , A xx and A yy of the charge-exchange reaction 1 H( d , 2 p) n have been measured at E d = 200 and 350 MeV up to excitation energies ( E x) of 8 MeV in the final pp system. The good agreement observed between the experimental dependence of the cross section and analysing powers upon E x and the predictions of an impulse approximation calculation improves with increasing beam energy. The large experimental figures of merit found for A xx and A yy demonstrate that this reaction can be used as the basis of a new deuteron tensor polarimeter in the 200–400 MeV energy range.
