Systematic study of the energy of vanishing flow: Role of equations of state and cross sections

Abstract

We present a systematic study of the energy of vanishing flow by considering symmetric colliding nuclei (between ${}^{12}$C and ${}^{238}$U) at normalized impact parameters using variety of equations of state (with and without momentum dependent interactions) as well as different nucleon-nucleon cross sections. A perfect power law mass dependence is obtained in all the cases which passes through calculated points nicely. Further, the choice of impact parameter affects the energy of vanishing flow drastically, demanding a very accurate measurement of the impact parameter. However, the energy of vanishing flow is less sensitive towards the equation of state as well as its momentum dependence.
