Isoscaling behavior in fission dynamics

The fission processes of {sup 112}Sn+{sup 112}Sn and {sup 116}Sn+{sup 116}Sn are simulated with the combination of the Langevin equation and the statistical decay model. The masses of two fission fragments are given by assuming the process of symmetric fission or asymmetric fission by Monte Carlo sampling with the Gaussian probability distribution. From the analysis of the isotopic/isotonic ratios of the fission fragments from both reactions, the isoscaling behavior has been observed and investigated in detail. Isoscaling parameters {alpha} and {beta} are extracted as a function of the charge number and neutron number, respectively, in different widths of the sampling Gaussian probability distribution. It seems that {alpha} is sensitive to the width of fission probability distribution of the mass asymmetrical parameter, but {beta} is not. Both {alpha} and {beta} drop with increasing beam energy and reduced friction parameter.
