The double differential cross-sections of Li, 7,9Be and B ions emitted in the interaction of 12C with 93Nb at incident energies varying from 200 to 400 MeV show that these intermediate-mass fragments are produced by two different mechanisms: the fragmentation of the projectile and the coalescence of nucleons during the thermalization of the intermediate nuclei produced in the complete and incomplete fusion of carbon and niobium. These results confirm those of previous investigations of our group and are well explained by the theories which we have proposed to describe these two reaction mechanisms.

Abstract

The double differential cross-sections of Li, 7,9Be and B ions emitted in the interaction of 12C with 93Nb at incident energies varying from 200 to 400 MeV show that these intermediate-mass fragments are produced by two different mechanisms: the fragmentation of the projectile and the coalescence of nucleons during the thermalization of the intermediate nuclei produced in the complete and incomplete fusion of carbon and niobium. These results confirm those of previous investigations of our group and are well explained by the theories which we have proposed to describe these two reaction mechanisms.
