Description
The major goals of modern superheavy element physics are the production of superheavy elements with Z=119, 120 and the synthesis of neutron-enriched isotopes, thereby advancing to the center of the “island of stability” (the neutron shell with N=184).
In this talk, a multidimensional dynamical model of nucleus-nucleus collisions based on the Langevin equations [1,2] has been used for analysis of reactions of 48Ca ions with actinide target nuclei. The cross sections of capture and fusion as well as the cross sections of evaporation residues for two combinations of colliding nuclei 48Ca+244Pu and 48Ca+248Cm have been studied. The possibilities of obtaining new neutron-enriched isotopes of superheavy elements in pxn channels have been analyzed.
The analysis of the competition of quasi-fission and fusion-fission processes in the reactions leading to the formation of 119 and 120 elements has been done in the framework of the dynamical model.
