Abstract.

The double differential cross-sections of Li, 7,9 Be and B ions emitted in the interaction of 12 C with 93 Nb 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.
