The effects of mean field and two-body collision on the radial expansion energy

The expansion energy has been studied by using BUU model based on the Skyrme interaction to obtain the information of equation of state. The effects of radial expansion energy on the mean field and two-body collision have been discussed. The results are that at intermediate energy heavy ion collision the radial expansion energy is sensitive to effective massm* and insensitive to the incompressibility. The reasonable effects massm*=0.8 m is obtained by comparison of expansion energy with experiment. Cross section has a little influence on the expansion energy and the effect of cross section on expansion energy increases with increasing beam energy.
