Description

The systems 20Ne+sup(nat)Re at 124 and 206 MeV and 40Ar+165Ho at 192 and 197 MeV were used to produce the 205At nucleus with different populations of angular momentum. The mass distributions of the fission products were measured. After allowing for the effects of temperature and neutron evaporation, it is found that the widths of the mass distributions increase considerably when the fission barrier disappears. Comparison of the results obtained here with those of other authors suggests that a third intermediate mechanism exists between fission and the highly inelastic collisions. (author)
