Abstract

Based on the model of nucleon associations, the two-nucleon transfer reaction (p, t) is considered in intermediate nuclei. The interaction between the nucleons is local and short-range, and the bineutron association already exists in the nucleon. The internal states of the incident proton, departing triton, and any intermediate association states are assumed to be completely symmetric S-states. Investigations are performed with distorted plane waves of the proton and triton, and the assumption is made that there is no exchange by nucleons among nucleon fragments. The differential cross sections calculated on the basis of this approach are presented, and these results demonstrate that the association model allows one to explain qualitatively the experimental data on particle scattering. Some possible directions of further study of direct nuclear reactions on the basis of the model are discussed.
