/sup 28/Si+/sup 12/C fusion reactions at high energies

We present a model based on the direct reaction concept which is able to describe the fusion cross section consistently throughout the entire range of the measured energies from the sub-barrier region to the very high energies where the cross section decreases linearly as the inverse of the center of mass energy. The model is applied to the fusion reaction of /sup 28/Si with /sup 12/C where Harmon et al. measured the cross section at energies up to three times the Coulomb barrier
