Investigating nuclear dissipation properties at large deformations via excitation energy at scission
Using the stochastic Langevin model coupled with a statistical decay model,we study nuclear dissipation properties at large deformations with excitation energy at scission（E＊sc） measured in experiments.It is found that the postsaddle dissipation strength required to fit E＊sc data is 12＊10^21 s^-1for...

| description | Using the stochastic Langevin model coupled with a statistical decay model,we study nuclear dissipation properties at large deformations with excitation energy at scission（E＊sc） measured in experiments.It is found that the postsaddle dissipation strength required to fit E＊sc data is 12＊10^21 s^-1for254;256Fm and 6＊1021 s-1for189Au,which has a smaller postsaddle deformation than the former heavy nucleus,showing a rise of nuclear dissipation strength with increasing deformation. |
