A DYNAMICAL METHOD IN DEEP IN ELASTIC COLLISION OF HEAVY IONS

A method correlating the dynamical equations with the diffusion equations is developed in this paper to explain the dissipations and fluctuations of heavy ion collisions. Considering the degrees of freedom about the relative motion, rotation and asymmetric mass, the relation between the frictional and diffusion tensors is obtained.
Some imformations of deep inelastic collisions in three reaction systems are obtained by solving coupling equations numerically. The calculated results show that there are orbiting effects in the reaction systems of ⁸⁶Kr(8.18MeV/A)+¹⁶⁶Er and ⁸⁴Kr(8.5MeV/A)+¹⁶⁵Ho and there is strong focusing effect in the reaction system of ¹³⁶Xe(8.31MeV/A)+²⁰⁹Bi. But the calculated results are in agreement with the experimental data only for larger partial waves. The nuclear force and diffusion coefficients must be studied further.
