    "abstract": "The fusion-fission process in the superheavy mass region is studied\nsystematically by solving the time evolution of nuclear shape in\nthree-dimensional deformation space using the Langevin equation. By analyzing\nthe trajectory in the deformation space, we identify the critical area when the\ntrajectory\u0027s destination is determined to be the fusion or the quasi-fission\nprocess. It is also clarified that the potential landscape around the critical\narea is crucial for estimating the fusion probability, and its dependence on\nthe atomic number is presented.",
