Abstract

Light-particle emission in the fusion reactions in the system ${}^{14}N$ + ${}^{27}{Al}$ at 100 MeV has been studied with use of coincident techniques. Comparison of the data with a statistical model accounts for the energy and angular distributions of the products, the particle multiplicities, and the dealignment in the evaporation cascade. However, (18±5)% of the evaporation residue cross section is of nonequilibrium origin and is interpreted in the framework of preequilibrium emission from complex configurations.
