Features of Nuclear Reactions with Light Weakly Bound Nuclei at Energies Near the Coulomb Barrier

Abstract

Experiments for studying the cross sections of fusion and transfer reactions involving beams of halo ( 6 He), cluster ( 6 Li and 7 Li), and loosely bound ( 3 He) nuclei and nuclei of light and heavy elements are presented. The analysis of the experimental cross sections for these reactions was undertaken. The specific features of the behavior of the cross sections of evaporation residual nuclei and transfer reaction products at energies near the Coulomb barrier were observed. In particular, there was an increase in the fusion cross sections with halo nuclei at sub-barrier energies. The neutron and cluster transfer cross sections in the reactions with cluster nuclei reach their maximum values at an energy near the Coulomb barrier.
