Abstract：
The mass number distributions of three fragments from the ternary fission of the system ¹⁹⁷Au+¹⁹⁷Au are reproduced rather well by using the improved quantum molecular dynamics (ImQMD) model without any adjusting parameter. It is found that the probability of ternary fission evidently depends on the incident energy and the impact parameter, and the two-body dissipation is the main mechanism responsible for the formation of the third fragment with comparable mass.
