This investigation aims to find an appropriate dinuclear system for the formation of 296119 superheavy compound nucleus.By studying the driving potential and measuring the capture cross section of the reactions,the evolution of the dinuclear system can be understood.In this study,we obtained capture,fusion,and evaporation residue cross sections and survival probability at energies near the Coulomb barrier for four reactions,namely 45Sc + 251Cf,42Ca + 254Es,39K + 257Fm,and 3BAr + 258Md.Our calculations show that the reaction 38Ar + 258Md is a suitable choice for the formation of an element with 119 protons among the studied reactions from a theoretical viewpoint.
