A systematic semiempirical analysis is presented for excitation functions for complete fusion of comples nuclei. Barrier penetration is included as is the l dependence of the fusion radius. The general form of the proximity potential is assumed and small but important parameter adjustments are made to achieve a fit to experimental data. A correction is presented of s-wave barrier heights and radii for complete fusion. For Z/sub t/Z/sub p/ 5 500 these fusion radii are greater than the empirical reaction radii obtained at energies well above the barrier. This result implies weak surface absorption for Z/sub t/Z/sub p/ 5 500 and the contrary for higher Z/sub t/Z/sub p/.
