An estimate of the contribution to the cross section due to the break-up of a trapped complex in the reaction of S on Co and S on Ge

This paper deals with the contribution to the reaction cross section coming from the break-up of an interacting complex of two fragments which is trapped in a pocket of the relative potential acting between the fragments. Calculations for the systems S on Co and S on Ge are done by using the semi-classical expression of tunneling through the barrier and the statistical break-up probability. The results are discussed and conclusions about the reaction mechanism are drawn. (orig.)
