Analysis of the fusion mechanism in synthesis superheavy element 119 via ${}^{54}$Cr+${}^{243}$Am reaction

Abstract

The combined dinuclear system (DNS) and statistical model implanted in KEWPIE2 have been used to study the prospects for the synthesis of a superheavy element (SHE) with $Z=119$ in the ${}^{54}$Cr+${}^{243}$Am fusion reaction. The method of calculation has been verified by description of the evaporation residue cross sections measured for the ${}^{48}$Ca+${}^{243}$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.
