Dependence of Nuclear Flow on Different Parts of Nuclear Interaction Potential
Keywords:
Nuclear interaction potential, Nuclear flow, Mass asymmetry, Momentum dependent potential, Symmetry potentialAbstract
The dependence of nuclear flow on different parts of nucleon-nucleon interaction the potential has been investigated for different mass asymmetric reactions 129Xe + 124Sn (η = 0), 82Kr + 158Gd (η = 0.3), 56Fe + 184W (η = 0.5) and 35Cl + 205Tl (η = 0.7) by keeping Atotal= 240 units within the Quantum Molecular theoretical framework. The directed flow increases with the addition of momentum-dependent interactions and symmetry potential while the elliptical flow tends to decrease with the addition of these potentials. These results show that momentum-dependent interactions and symmetry potential have sizable effect on the magnitude of collective nuclear flow. A comparison between our calculations and experimental data for the energy dependence of
elliptical flow for 129Xe + 124Sn system reveals the importance of different components of nucleon-nucleon interaction potential in the reaction dynamics.
