Abstract：
A combined dynamical and statistical model has been applied to simulate the fission process of ¹¹²Sn+¹¹²Sn and ¹¹⁶Sn+¹¹⁶Sn. The mass distribution of the fission fragments is given by the Gaussian probability sampling. The isoscaling behavior has been observed from yield ratio of the fission fragments and the isoscaling parameter α and β have been extracted. It seems that the isoscaling parameters are sensitive to the width of fission probability and the beam energy as well as the deduce friction parameter.
