Modeling of nuclear reactions with Langevin calculations

Abstract

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 a diagonal correlation appears. This diagonal correlation could not be reproduced in our previous model that is before introducing $f_\text{ina}$ and $γ_\text{t}^{0}$ 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 $^{48}$Ti + $^{186}$W reaction system. As a result, $f_\text{ina}$ and $γ_\text{t}^{0}$ of model parameters were found to be key parameters for MAD. it was also found that the balance between $f_\text{ina}$ and $γ_\text{t}^{0}$ parameter values is important for the strong correlation between mass and angle.
