Fusion excitation functions have been measured spanning the entire barrier region in 1 MeV energy steps for the two systems {sup 40}Ca+{sup 192}Os,{sup 194}Pt. Precautions were taken to ensure sufficiently small errors to allow for extraction of the distribution of fusion barriers from the second differential of the product of {ital E} and {sigma}. These results are compared with coupled channels calculations which take into account the most important degrees of freedom of both projectile and target. The influence of the prolate deformation of {sup 192}Os and the oblate deformation of {sup 192}Pt as well as the octupole vibration of {sup 40}Ca is apparent. {copyright} {ital 1996 The American Physical Society.}
