Abstract
For the description of deep inelastic reactions between deformed nuclei we present a classical model with frictional forces. The frictional forces and moments are derived from an extended double-folding model of Tsang and have a finite range. The frictional forces dissipate energy and angular momentum. In order to show the symmetries of the frictional forces and to simplify dynamical calculations we develop a multipole expansion of the frictional forces and moments. The model is applied to the deep inelastic reaction of 238U on 238U at E lab = 7.42 MeV/amu. By averaging over the initial orientations of the intrinsic symmetry axes of the deformed nuclei, we calculate the double-differential cross section d 2σ dE dθ cm , the differential one dσ dΩ , and th total one for the deep inelastic collision.
