Abstract
The fusion excitation functions for 28Si + 28Si and 40Ca + 40Ca are determined using a fully dynamical calculation. This calculation includes a careful treatment of entrance channel deformations and the deformation dependant inertias in both the one-body and two-body regimes. It is shown that deformation, deformation dependent inertias and wall friction affect the fusion excitation function in a fundamental way. We also perform the calculation with a weaker wall friction (surface friction) and show that only the strong wall friction is consistant with the experimental data.
