AMD study of the EOS of asymmetric nuclear matter in nuclear collisions

The effects of the equation of state of asymmetric nuclear matter on the nuclear collisions are discussed based on the microscopic calculations by antisymmetrized molecular dynamics. In the calculations with the different effective interactions corresponding to different density dependence of the symmetry energy, the isospin effects in high and low density stages are seen in the collisions of neutron-rich unstable nuclei as well as in collisions of heavy stable nuclei with large N/Z.
