Role of equation of state and clusterization algorithms on nuclear vaporization
Abstract
By using the Quantum Molecular Dynamics (QMD) model, a study on the nuclear vaporization in 40Ca+40Ca collision is presented for different nuclear equations of state along with a systematic comparison of different clusterization methods based on simple spatial correlations, spatial-momentum correlations, mass dependent binding energy cuts and Simulated Annealing Clusterization Algorithm (SACA). The effect of different nuclear equations of state i.e., Soft, Hard and Soft with Momentum Dependent (SMD) interactions on the energy of onset of vaporization for 40Ca+40Ca collisions is predicted by investigating gas/liquid content and probability of vaporization versus incident energy behavior. These two observables probe the critical point of nuclear vaporization very well. Further outcome of different clusterization algorithms on the energy of onset of nuclear vaporization is also probed and a comparison of calculations with the experimental data for 16O+80Br and 16O+107Ag collisions is carried out for different clusterization algorithms.
