Abstract
A theoretical analysis of flow disappearance in heavy-ion collisions i s performed in the relativistic Vlasov-Uehling-Uhlenbeck (RVUU) approa ch. We find that the energy of vanishing flow (EVF) is insensitive to the impact parameter b and the momentum dependent mean field. By compa ring the numerical results to the experimental data, a nucleon-nucleon cross section sigma = (1.4 +/- 0.2) sigma(f) is inferred where sigma( f) is the energy-dependent free nucleon-nucleon cross section.
