摘要：

Fusion cross sections for the reactions +Ca40 and +Ca44 have been measured between 10 and 27 MeV (lab) via the detection of the radiation of the evaporation residues. At maximum the cross sections are about 1170 mb for +Ca44 and about 970 mb for +Ca40. This difference supports recent optical-model and semiclassical interpretations that the well-known anomalous large-angle scattering results from different absorption strengths for these two systems. © 1979 The American Physical Society.
