A theoretical study on quasifission and fusion-fission processes in heavy-ion collisions

The stochastic mean-field (SMF) technique beyond the time-dependent-Hartree-Fock approach is used to explore the primary mass yields of quasifission fragments in the 58Fe+208Pb\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${}<^>{58}\text {Fe}+{}<^>{208}\text {Pb}$$\end{document} reaction at the bombarding energy Ec.m.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$E_{\text {c.m.}}$$\end{document} = 238.5 MeV, 50Ti+208Pb\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${}<^>{50}\text {Ti}+{}<^>{208}\text {Pb}$$\end{document} reaction at Ec.m.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$E_{\text {c.m.}}$$\end{document} = 237 MeV, and in the 36S+238U\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${}<^>{36}\text {S}+{}<^>{238}\text {U}$$\end{document} reaction at Ec.m.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$E_{\text {c.m.}}$$\end{document} = 151.1 MeV. A statistical de-excitation model, GEMINI++ code, is used for calculating the primary mass yields of fusion-fission fragments after the de-excitation processes of primary products in the same systems. The obtained results are compared with available experimental data. Analysis of SMF and GEMINI++ calculations exhibit a good agreement with the corresponding experimental results, signifying the reliability of our approach in describing the fragment mass yields for the specific reaction systems.
