Dynamical Properties of the New Ternary Fission in Collisions of 197Au+197Au at 15 MeV/Nucleon

Dynamical Properties of the New Ternary Fission in Collisions of 197Au+197Au at 15 MeV/Nucleon

The dynamical properties of the new ternary fission in heavy 197Au+197Au at 15 MeV/nucleon have been investigated by using the improved quantum molecular dynamics model. The dependencies of the production probability, lifetime, the time interval, and angular distribution on the impact parameter are...
