Fusion excitation functions spanning the entire barrier region in 1 MeV energy steps for the two systems {sup 40}Ca + {sup 192}Os, {sup 194}Pt are presented. The results of fission fragment angular distribution measurements for fusion-fission of {sup 40}Ca + {sup 197}Au at several projectile energies within the barrier region are also presented. The fusion data is 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.
