The cross-sections and angular distributions of the D—D reactions between 150 and 450 keV

Abstract

A thin gas target was used and the 3 He and 3 H particles from the reactions were counted in two proportional counters which were rotated to make angles between 20 and 135° (in the centre-of-mass system) with the incident deuteron beam. In contradiction to data previously published for this energy range, the angular distributions of the reactions are different, the asymmetry of the neutron-producing reaction being the greater. The total cross-section of the neutron reaction is greater than that of the proton reaction; the ratio of the cross-sections increases with bombarding energy.
