摘要：

The yield distributions of neutron-induced fission of actinides were calculated and evaluated by using the improved scission-point model with considering octupole deformation of fragments. We studied the influence of the octupole deformation on the asymmetric yields of actinides fission. The more probable scission configuration is the pear-shaped heavy fragments rather than more spherical shape. We used the improved scission model to calculate the peak of charge and neutron distributions and compared results with the experimental data. The results confirm that the main asymmetric fission mode of the heavy actinides fission is indeed characterized by "ZH & AP; 54." The protons configuration of heavy fragment plays a dominant role in asymmetric fission of actinides.
