Abstract
Transport equations of the Fokker-Planck type are derived from a master equation for deeply inelastic collisions. Using the method of spectral distributions, the transport coefficients are calculated for symmetric fragmentations. Analytic formulas are given for the memory time, for the energy-drift coefficient and for the diffusion coefficients which correspond to the excitation of the fragments and the transfer of nucleons. These expressions contain parameters of the basic interaction matrix elements only, which describe excitations and transfers. Agreement with experimental data is obtained for reasonable values of these interaction parameters. Production cross-sections are predicted for superheavy nuclei in the deeply inelastic collisions U+U and U+Cf.
