Speaker: V.A.Rachkov, (on Candidate's thesis)
This work concerns the theoretical study of nuclear fusion at energies near the Coulomb barrier. Special attention is devoted to the study of nuclear system DOF cross-effect (collective excitations and neutron transfers) on fusion at sub-barrier energies. A large set of experimental data on fusion cross-sections are explained. This work is based on the empirical channel coupling model which takes into consideration the possibility of neutron rearrangement. V.I.Zagrebaev's model was updated in this work.
The way of taking neutron rearrangement into account within the strong channel coupling method was realized in this work which made it possible to describe thin structure of excitation functions of nuclear fusion cross-section.
The cross-sections of formation of new isotopes of heavy and superheavy elements with Z=102-107 in the neutron-excess projectiles and actinide targets fusion reactions were calculated.
