摘      要：A model for cold-fusion reactions related to the synthesis of super-heavy nuclei in collisions of heavy projectile-nuclei with a ^(208)Pb target nucleus is *** the framework of this model,the production of the com-pound nucleus by two paths,the di-nuclear system path and the fusion path,are taken into account *** formation of the compound nucleus in the framework of the di-nuclear system is related to the transfer of nucle-ons from the light nucleus to the heavy *** fusion path is linked to the sequential evolution of the nuclear shape from the system of contacting nuclei to the compound *** is shown that the compound nucleus is mainly formed by the fusion path in cold-fusion *** landscape of the potential energy related to the fusion path is discussed in *** landscape for very heavy nucleus-nucleus systems has an intermediate state,which is linked to the formation of both the compound nucleus and the quasi-fission *** decay of the intermediate state is taken into account in the calculation of the compound nucleus production cross sections and the quasi-fission cross *** values of the cold-fusion cross sections obtained in the model agree well with the experimental data.
