Cluster Transfer Reactions between Complex Nuclei

Abstract

Cluster transfer reactions between complex nuclei are discussed in a simple semiclassical approximation. For energies below the Coulomb barrier nuclear distortions are neglected, and the results coincide with the "tunneling model" predictions of Breit. For energies above the Coulomb barrier, distortions are taken into account by a finite-range diffraction model. Closed-form expressions are obtained for the angular distribution of the reaction products and for the transfer excitation function. Coulomb effects are shown to play a dominant role in determining the main features of the reaction. Good agreement with experimental data is obtained.
