Dependence of the energy of vanishing flow on different components of the nuclear potential

Abstract

The contribution of various components of potential towards balance energy is analyzed for the reactions of ${}_{26}^{58}\text{Fe}+{}_{26}^{58}\text{Fe}$, ${}_{28}^{58}\text{Ni}+{}_{28}^{58}\text{Ni}$, ${}_{36}^{86}\text{Kr}+{}_{41}^{93}\text{Nb}$, and ${}_{79}^{197}\text{Au}+{}_{79}^{197}\text{Au}$ using an isospin-dependent quantum molecular dynamics (IQMD) model. We show that the balance energy changes with the addition of various components of potentials. Our calculations for the considered energy range clearly demonstrate the dominance of the Coulomb potential and momentum-dependent interactions over the other potentials for the lighter colliding systems. However, the contribution of the symmetry potential also becomes significant while handling heavier nuclei.
