Abstract
Elastic scattering angular distribution and 180° c.m. excitation function are rather well reproduced just above the Coulomb barrier by a heavy-ion nuclear potential having a repulsive core at short distances and a very strong attractive behavior at the nuclear surface. An important prediction of this potential, a precipitous drop in differential cross section at 180°, is verified experimentally.
