โœฆ Synopsis

A model of competition between complete fusion and quasifission channels in fusion of two massive nuclei is extended to include the influence of dissipative effects on the dynamics of nuclear fusion. By using the multidimensional Kramers-type stationary solution of the Fokker-Planck equation, the fusion rate through the inner fusion barrier in mass asymmetry is studied. Fusion probabilities in symmetric ~Zr+9ยฐZr, l~Mo+lยฐยฐMo, uยฐPd+UยฐPd, 136Xe+136Xe, almost symmetric 86Kr+136Xe and HยฐPd+~36Xe reactions are calculated. An estimation of the fusion probabilities is given for asymmetrical 62Ni+2ยฐsPb, 7ยฐZn+2ยฐspb, 8ZSe+2ยฐsPb, and 48Ca+244pu reactions used for the synthesis of new superheavy elements. @ 1997 Elsevier Science B.V.

We review the theoretical methods to evaluate fusion cross sections in collisions of weakly bound nuclei. We point out that in such collisions the coupling to the breakup channel leads to the appearance of different fusion processes. The extension of the coupledchannel method to coupling with the co
