Experimental fusion barrier distributions reflecting projectile octupole state coupling to prolate and oblate target nuclei

Fusion excitation functions have been measured spanning the entire barrier region in 1 MeV energy steps for the two systems Ca-40 + Os-192 + Pt-194. 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 E and sigma. These results are compared with coupled channel calculations which take into account the most important degrees of freedom of both projectile and target. The influence of the prolate deformation of Os-192 and the oblate deformation of Pt-192 as well as the octupole vibration of Ca-40 is apparent.
