摘要
Recent developments on reaction mechanisms in fusion of massive systems are briefly reviewed, especially on a two-step model. The fusion hindrance observed experimentally is simply explained in connection with the fluctuation-dissipation dynamics of shape evolutions and of two-body collisions. Examples are given for fusion excitation functions and compared with the available data on Ca-48 + actinide target systems.
