摘要：

Fusion excitation functions spanning the entire barrier region in 1 MeV energy steps for the two systems Ca-40 + Os-192, Pt-194 are presented. The results of fission fragment angular distribution measurements for fusion-fission of Ca-40 + Au-197 at several projectile energies within the barrier region are also presented. The fusion data are of high enough precision to allow for extraction of the distribution of fusion barriers from the second differential of the product of E and sigma. Basic coupled channels calculations which are in quite good agreement with the data are shown and discussed.
