2-BODY FINAL-STATES IN D + D INTERACTION IN 50-85 MEV INCIDENT ENERGY-RANGE

Angular distributions of the H2(d, d)H2, H2(d, p)H3, and H2(d, n)He3 reactions at six incident energies in the 50-85 MeV range have been measured. The H2(d, p)H3 reaction data have been analyzed in terms of the plane-wave Born-approximation theory. A smooth cutoff in the partial wave expansion of the reaction matrix has been introduced to allow the suppression of the low angular momentum components. The calculated angular distributions obtained with a constant cutoff angular momentum lco=3 show reasonably good agreement with the experimental data in the whole 50-85 MeV energy range. This is consistent with the peripheral character of the reaction.
