Abstract

The combined dinuclear system (DNS) model and statistical model incorporated in kewpie2 have been used to study the prospects for the synthesis of a superheavy element (SHE) with $Z=119$ in the $^{54}\mathrm{Cr}+^{243}\mathrm{Am}$ fusion reaction. The method of calculation has been verified by description of the evaporation residue cross sections measured for the $^{48}\mathrm{Ca}+^{243}\mathrm{Am}$ reaction. The calculated results of the partial and total cross sections for the complete fusion, quasifission, fast fission, and evaporation residues formation for both reactions are discussed.
