The scission point model has been used to calculate the total kinetic energy (TKE) as a function of fission fragments (TKE/A) for photofission reactions. By comparing the calculated TKE values with the available experimental data, the deformation parameters of the fission fragments are obtained in the scission point model. The results show that the deformation parameters of the fission fragments have a large change near the symmetrical region. TKE distribution has been investigated for neutron fission, spontaneous fission, and photofission to predict actinide TKE distribution. This indicates that the TKE distribution depends on the mass and atomic number of compound nuclei and, of course, the excitation energy. The odd-even effect plays an important role in predicting TKE distribution behavior. Also, TKE distribution has a similar trend for all isotopes and the TKE distribution of spontaneous fission is significantly different from the TKE distribution of photofission. At last, the total kinetic energy distributions for the photofission fragments of light actinides are evaluated in the scission point model.

轻act系元素光裂变的动能分布

分裂点模型已用于计算作为光裂变反应的裂变碎片（TKE / A）的函数的总动能（TKE）。通过将计算出的TKE值与可用的实验数据进行比较，在裂变点模型中获得了裂变碎片的变形参数。结果表明，裂变碎片的变形参数在对称区域附近变化较大。已经对中子裂变，自发裂变和光裂变的TKE分布进行了研究，以预测act系元素TKE的分布。这表明，TKE分布取决于化合物核的质量和原子序数，当然还取决于激发能。奇偶效应在预测TKE分布行为中起重要作用。也，TKE分布对所有同位素都有相似的趋势，并且自发裂变的TKE分布与光裂变的TKE分布明显不同。最后，在断裂点模型中评估了轻act系元素的光裂变碎片的总动能分布。
