Background: The cross section for forming a heavy evaporation residue in fusion reactions depends on the capture cross section, the fusion probability, P-CN, i.e., the probability that the projectile-target system will evolve inside the fission saddle point to form a completely fused system rather than reseparating (quasifission), and the survival of the completely fused system against fission. P-CN is the least known of these quantities. Purpose: We want to determine P-CN for the reactions of 101.2 MeV O-18, 147.3 MeV Mg-26, 170.9 MeV Si-30, and 195.3 MeV S-36 with Au-197. Methods: We measured the fission fragment angular distributions for these reactions and used the formalism of Back to deduce the fusion-fission and quasifission cross sections. From these quantities we deduced P-CN for each reaction. Results: The values of P-CN for the reactions of 101.2 MeV O-18, 147.3 MeV Mg-26, 170.9 MeV Si-30, and 195.3 MeV S-36 with Au-197 are 0.66, 1.00, 0.06, and 0.13, respectively. Conclusions: The new measured values of P-CN agree roughly with the semiempirical systematic dependence of P-CN upon fissility for excited nuclei.
