Abstract

Experimental results on excitation functions for complete-fusion and transfer reactions in the interaction of 6He and 6,8,9Li nuclei with various target nuclei are presented. Data on fusion-reaction cross sections in the case of 6He differ strongly from the predictions of the statistical model. A strong enhancement of the cross section at barrier energies is observed for this reaction channel. Also, an increase in the cross sections for neutron-transfer reactions (in the case of 6He and 8,9Li beams) and deuteron-transfer reactions (in the case of 6Li) is observed in the deep-subbarrier energy region. The results are discussed from the point of view of the effect of the cluster structure of nuclei on the probability of interaction at barrier energies. The results of employing heavy-ion beams in new technologies are presented.
