Nuclear interaction potential, Nuclear flow, Mass asymmetry, Momentum dependent potential, Symmetry potentialAbstract
Background: During a heavy ion reaction, the interaction between projectile and target nucleons takes place and the outcome of a reaction depends strongly on the nuclear interaction potential, which is the imperative factor in deciding the fate of reaction. Several efforts have been made in this direction to explore number of phenomena. One of the most sought after phenomena in this direction is the collective flow and its various forms.
Purpose: This study aims to investigate the dependence of collective nuclear flow on different parts of nucleon-nucleon interaction potential for different mass asymmetric reactions ^{129}Xe + ^{124}Sn (\eta = 0), ^{82}Kr + ^{158}Gd (\eta = 0.3), ^{56}Fe + ^{184}W (\eta = 0.5) and ^{35}Cl + ^{205}Tl (\eta = 0.7) by keeping Atotal=240Atotal=240 units. Two different signatures of collective flow have been studied: a) bounce-off of compressed matter in the reaction plane called directed flow and b) squeeze-out of the participant matter out of the reaction plane called elliptical flow.
Methods: The present work is carried out within the Isospin dependent Quantum Molecular Theoretical Framework in which total interaction potential is composed of Skyrme potential, Yukawa Potential, Coulomb Potential, Momentum dependent interaction potential and symmetry potential.
Results: The findings reveal that the directed flow increases with addition of momentum dependent interactions and symmetry potential while the elliptical flow tend to decrease with addition of these potentials.
Conclusions: Both the momentum dependent interaction potential and symmetry potential have sizable affect on the magnitude of collective nuclear flow. A comparison between our calculations and experimental data for the energy dependence of elliptical flow for ^{129}{50}Xe + ^{124}{50}Sn reaction reveals that all the components of nuclear potential are necessary to explain the reaction dynamics.
