Description
A semi-classical transport model, namely, quantum molecular dynamics (QMD) model, is employed for the theoretical study of nuclear dynamics in case of Au197 + Au197 collisions at different beam energies from 20 to 1000 MeV/nucleon and at impact parameters from b = 0 to 13 fm using soft equation of state (EOS). In particular, we study the various quantities like average and maximum density, anisotropic ratio, participant-spectator matter, relative momentum, rapidity distribution, collision rate, time of maximal density and their energy and impact parameter dependence. Our findings clearly indicate a significant energy and impact parameter dependence of all quantities. The time of maximal average density and maximum density follow a power law with incident energy. Interestingly, we observed that the variation of the impact parameter leads to drastic change in the participant/spectator matter up to 400 MeV/nucleon, whereas beyond 400 MeV/nucleon, nearly impact parameter independent results are found. Dr. Supriya Goyal is Ph.D in Theoretical Nuclear Physics from Panjab University, Chandigarh, India. She has 13 years of experience in teaching and research at GSSDGS Khalsa College Patiala, Punjab, India. She has done M.Ss. (Hons) Physics from Panjab University Chandigarh Campus and is CSIR-UGC NET qualified.
