Abstract
The prominent side peak observed in nuclear reaction data induced by massive heavy ions such as Ar, Kr, and Xe is observed to be dominated by quasielastic processes and these processes are interpreted theoretically in terms of the distorted-wave Born approximation (DWBA). Variations of peak location with energy and projectile mass and charge are well reproduced by sample DWBA calculations for particle transfer. Quantal and classical contributions to the angular widths are discussed.
