The properties of fully energy-damped processes (deep-inelastic orbiting, fusion-evaporation, and fusion-fission processes) have been investigated in the nearly mass-symmetric entrance-channel [sup 23]Na + [sup 24]Mg reaction leading to the [sup 47]V compound nucleus. By comparison with previous data for the mass-asymmetric [sup 35]Cl +[sup 12]C reaction forming the same compound system at the same excitation energy, no entrance-channel effects are observed in either the evaporation residue or the fusion-fission yields. This is in contrast to the situation with the [sup 28]Si +[sup 12]C and [sup 24]Mg +[sup 16]O reactions where an orbiting process is evident. The asymmetrical elemental distributions of the fusion-fission fragments of the mass[ital A]=47 system are well described by a transition-state model that accounts for the spin and mass-asymmetry dependence of the fission saddle point.
