Abstract

An analytical form is given for the entire energy range of quasielastic fragment spectra produced in intermediate-energy heavy-ion collisions. The fit parameters are related to physical quantities such as the probability of direct fragmentation versus damped fragmentation and the momentum width of the direct fragmentation peak. The formulation is applied to fragment spectra at 10° from the 14N+165Ho reaction at E/A = 35 MeV. It is suggested that Coulomb deflection and impact-parameter selection have a decisive effect on fragment spectra produced in peripheral collisions. The smaller the Z/A of the detected fragment at a given angle, the smaller the impact parameter of the reaction.
