Possibilities of producing superheavy nuclei in multinucleon transfer reactions based on radioactive targets

The multinucleon transfer (MNT) process has been proposed as a promising approach to produce neutron-rich superheavy nuclei (SHN). MNT reactions based on the radioactive targets ²⁴⁹Cf, ²⁵⁴Es, and ²⁵⁷Fm are investigated within the framework of the improved version of a dinuclear system (DNS-sysu) model. The MNT reaction ²³⁸U + ²³⁸U was studied extensively as a promising candidate for producing SHN. However, based on the calculated cross-sections, it was found that there is little possibility to produce SHN in the reaction ²³⁸U + ²³⁸U. In turn, the production of SHN in reactions with radioactive targets is likely.
