Abstract

We present a complete set of eight differential cross sections of the reactions H2(d, n)He3 and H2(d, p)H3 in the 0-60° c.m. angular range for incident deuteron momenta between 1.1 and 2.5 GeV/c. A simple phenomenological interpretation of the energy dependence of the total cross section σT and of dσdt at fixed t shows, in the reaction, the contribution of a nucleon exchange process to which we must add a mechanism implying the Δ33 resonance excitation in the direct channel.

NUCLEAR REACTION H2(d, n)He3, H2(d, p)H3; Ed=0.31.25 GeV; measured σ(Ed, θ); intermediate energy; phenomenological analysis of the baryonic exchange mechanisms.
