Quasielastic nucleon-transfer cross sections have been mea- sured at energies 35% above the Coulomb barrier for 58,64Ni + 112,116,120,124Sn. The systematic trends were studied over the range of systems, which span a factor of 2 in neutron excess N-Z. The observed magnitude of the cross sections and their surface localization suggest that quasielastic processes play an important role in the average nucleus-nucleus potential, a quantity of considerable recent interest in near-barrier collisions of heavy systems.
