Nuclear dynamics at the geometry of vanishing flow in heavy-ion collisions

Abstract

We study the time evolution and mass dependence of various quantities (such as average and maximum central density, collision dynamics, participant spectator matter, and average and maximum temperature) at the geometry of vanishing flow (GVF) throughout the mass range between 80 and 262 units. We find that the reaction time at 100 MeV/nucleon of the geometry of vanishing flow is smaller for lighter nuclei compared to heavier ones. All the quantities can be parameterized by a power law dependence. The maximal values of corresponding quantities are also shifted accordingly.
