Abstract

The azimuthal dependence of mean fragment in Au+Au and Xe+CsI systems was investigated as function of incident energy and centrality. The flow energy values along different azimuthal directions were observed as snapshots of fireball expansion at different exposure time. Less transverse energy was also produced for same number of participating nucleons from heavier system. The nuclear equation of state (EOS) was derived using Boltzmann-Uehling-Uhlenbeck (BUU) calculations under momentum-dependent fields.
