Modeling of Nuclear Reactions with Langevin Calculations

The mass angle distribution shows a strong correlation between mass and angle when quasifission events are dominant. Therefore, as long as quasifission events are dominant, the mass angle distribution is characterized in that diagonal correlation appears. This diagonal correlation could not be reproduced in our previous model that is before introducing $${{f}_{{{\text{ina}}}}}$$ and $$\gamma _{t}^{0}$$ model parameters. In this study, we clarify the indeterminate parameters included in the model to reproduce the diagonal correlation appearing in the mass angle distribution in the 48Ti + 186W reaction system. As a result, $${{f}_{{{\text{ina}}}}}$$ and $$\gamma _{t}^{0}$$ of model parameters found to be key parameters for MAD. it was also found that the balance between $${{f}_{{{\text{ina}}}}}$$ and $$\gamma _{t}^{0}$$ parameters values is important for the strong correlation between mass and angle.
