Effect of momentum dependent interactions and nucleonic cross-section on directed flow (v1)

The descriptive analysis for the effect of momentum dependent interactions and nucleonic cross-section (isospin dependent and isospin-independent) on the neutron-proton directed flow (v1), within the framework of the isospin dependent quantum molecular dynamics model is presented. Our study shows that, the directed flow of both neutrons and protons is affected by the momentum dependence of nuclear equation of state and the isospin dependence of nucleon-nucleon cross-section. A soft momentum dependent (SM) equation of state is found to be more compatible with the experimental data.
