One and two charge stripping reactions in the 12C+197Au and 16O+197Au systems at large distances.

Abstract

One- and two-charge-transfer reactions were studied in the {sup 12}C+{sup 197}Au and {sup 16}O+{sup 197}Au systems at bombarding energies around the Coulomb barrier. Transfer probabilities for the same Coulomb reduced radius, extracted from angular distribution measurements, show a strong dependence on the bombarding energy and are interpreted within a semiclassical model. Quasielastic scattering data are analyzed in terms of an energy-dependent optical model. {copyright} {ital 1996 The American Physical Society.}
