Role of Mass Asymmetry on the Energy
of Peak Intermediate Mass Production
and Its Related Dynamics
Sakshi Sharma, Rohit Kumar, and Rajeev K. Puri
Abstract We study various reactions of different projectiles with fixed targets of
124 Sn and
197 Au using Isospin-dependent Quantum Molecular Dynamics (IQMD)
model. Here, the mass dependence of energy of peak production and peak IMFs
multiplicity is investigated for
124 Sn and
197 Au target reactions. It is observed that
the energy of peak production increases on moving toward low mass projectiles
for both
124 Sn and
197 Au target reactions with different slopes. Further, we study the
mass dependence of various fragments at the peak energy and power law dependence
of these fragments is observed. The study is further continued by investigating the
behavior of various other quantities (maximum and average density, collision rate,
maximum, and average temperature) at the energy of peak production. Our findings
indicate the power law dependence of these quantities at peak energy. Also, the
behavior of participant and spectator matter at peak energies for
124 Sn and
197 Au
target reactions is explored.
7.1 Introduction
Heavy-ion collisions (HICs) act as a significant probe to explore nuclear equation
of state (EOS) and provide information about the microscopic features of nuclear
matter. On the basis of energy, HICs are classified into different energy regimes, i.e.,
low, intermediate, and high energies. In low energy regime, the nuclear dynamics is
mainly governed by mean field, and fusion, fission, cluster radioactivity, formation of
super heavy nuclei are studied [1–6]. At high energies, nucleon-nucleon collisions
dominate the reaction dynamics and phenomena such as particle production, jet
