To study the thermal equilibrium in mass asymmetric nuclear reactions at intermediate energies

Abstract

In the present study, the variation of temperature (of the hot central region formed in the heavy ion collisions) with the scaled impact parameter and rotational effect has been analyzed for various mass asymmetric nuclear reactions under the influence of soft equation of state using Isospin-dependent Quantum Molecular Dynamics (IQMD) model. The notable rotational effect is observed from the phase space dynamics and from the local density profile of the two asymmetric colliding nuclei. Afterwards the simulations have been carried out for the various reactions at the fixed value of incident energy and colliding geometry i.e. bˆ for a fixed value of participant zone for each and every reaction. It has been observed that the T max avg increases with increase in the mass asymmetry. A marked influence of rotational effect has also been observed on the max T  avg for the various mass asymmetric reactions.
