| Projectile-like fragments produced in the reaction 129Xe + natCu and natSc at E/A = 30, 40, 50, and 60 MeV were detected using a new forward array, the Maryland Forward Array, for the Michigan State University 4 p array. The charge, energy and position of the fragments were measured. Inclusive energy, charge and velocity distributions, as well as mean charge and charge width as a function of energy, and mean velocity as a function of charge, were generated. In addition, the deflection functions for the systems were measured over the range of the detector.; The data are compared to the results of Tassan-Got's stochastic nucleon exchange model to see if a deep-inelastic process can produce the fragments seen in these reactions. In addition, a dynamic model, BUU, is used to see its predictions for peripheral collision reproduce the trends seen in the data.; At E/A = 30 and 40 MeV, a comparison of the data with Tassan-Got model calculations and an orbiting pattern in the deflection function suggest that the deep-inelastic reaction mechanism is occurring for both the Xe + Cu and Sc systems. At E/A = 50 MeV, the grazing angle for the Xe + Sc system falls inside the detector's inner radius, so no conclusion, based on the deflection function, about deep-inelastic process is made, however for the Xe + Cu system, the mean charge, charge width and mean velocity plots support the presence of deep-inelastic reaction. At E/A = 60 MeV, the grazing angle falls inside the detector's inner radius for both systems. However, the differences in the data suggests that the deep-inelastic process may no longer be occurring. |
