DYNAMIC APPROACH TO ANALYSIS OF ANGULAR DISTRIBUTIONS OF FISSION AND QUASIFISSION FRAGMENTS

The dynamic model is proposed for description of the angular distributions of quasifission fragments. The model is able to describe experimental anisotropy of the angular distributions of fissionlike fragments for the (32)S, (28)Si+(208)Pb reactions. It is also shown that the new model allows the description of the experimental mass-angular correlations in the quasifission fragment yields for the (64)Ni+(197)Au reaction at 383 and 418 MeV of incident energies. The analysis was performed with the angular momentum and deformation dependent relaxation time of the tilting mode. Information on the dinuclear system lifetimes were obtained.
