Abstract

We investigate the energy of vanishing flow (EVF) as a function of colliding geometry for various reactions and confront our theoretical calculations with available experimental data. Our findings using an isospin-dependent quantum molecular dynamics (IQMD) model reveal that measured energies of vanishing flow can be reproduced nicely by IQMD model calculations. We also analyze, in detail, the role of hard and soft equations of state (with and without momentum-dependent interactions) in transverse flow and its disappearance over a wide range of mass and impact parameters. Our investigations reveal that the mass dependence of the energy of vanishing flow at peripheral collisions can act as a useful probe to pin down the stiffness of nuclear matter.
