  The Improved Quantum Molecular Dynamics model is further developed by
introducing new parameters in interaction potential energy functional based on
Skyrme interaction of SkM$^{*}$ and SLy series. The properties of ground states
of selected nuclei can be reproduced very well. The Coulomb barriers for a
series of reaction systems are studied and compared with the results of the
proximity potential. The fusion excitation functions for a series of fusion
reactions are calculated and the results are in good agreement with
experimental data.
