Impact of momentum dependent equation of state and isospin-dependent cross-section on the neutron-proton Pt-differential elliptic flow
We made a descriptive theoretical analysis for the transverse momentum dependence of elliptic flow (ν2) of neutrons and protons within the framework of isospin-dependent quantum molecular dynamics (IQMD) model. Simulations are carried out for the symmetric reactions of 124Sn+124Sn and 197Au+197Au. We demonstrate the effect of momentum dependent interactions (MDI) as well as of nucleonic cross-sections (isospin-dependent & independent) on the elliptical flow. The MDI and different forms of cross-section are found to affect the elliptical flow of both protons and neutrons considerably.
