Dissociation of excited HT by collision with rare-gas atoms

Abstract

A simple hard-sphere model is used to study the fate of HT produced by reaction of hot tritium atoms with hydrocarbons in the presence of rare-gas moderators; the results suggest that HT may be produced by a high-energy stripping mode of reaction, but that much of this product may dissociate on collision with the moderator, resulting in some cases in an effective excitation function which is comparable to that required by the energy cut-off model.
