“…In the literature several studies have been made to study the fragmentation pattern and thermalization achieved in heavy-ion reactions. Puri and co-workers [6] studied multifragmentation at the energy of vanishing flow in central heavy-ion collisions and found a power law dependence of different fragment multiplicities at the energy of vanishing flow. In an another study, the degree of stopping is found to decrease with the increase in impact parameter as well as at very high energies [3].…”

Abstract. Using the isospin-dependent quantum molecular dynamics model, we study the stability of the fragments and the thermalization achieved in the collision of a neutronrich colliding pair at energies where the maximum production of intermediate mass fragments (E max c.m. ) occurs. In particular, we check the stability of fragments through the persistence coefficient and gain term and information about the thermalization and stopping is obtained via the relative momentum, anisotropy ratio, and rapidity distribution. Our findings show a weak dependence of these quantities on the neutron content of the colliding pair.

We aim to carry out the detailed study of system-size effects and momentum correlations by simulating the reactions of 12 C+ 12 C, Au at an incident energy of 400 MeV/nucleon and over entire colliding geometry from a central to an extreme peripheral one. A mass-independent role of the momentum correlations is reported for the entire periodic table. When averaged over all fragments, the effect of momentum correlations for central collisions is about 39%. All mass yields can be parametrized by a power law with 2 τ 3 which is in agreement with other theoretical and experimental studies.
