锕系核素的中子裂变截面是核反应堆、核工程设计等方面的重要核数据。到目前为止,虽然已经有了一定数量的裂变截面的实验测量数据,但是有些核素由于样品难以得到或者实验条件的限制,数据还很缺乏。因此在已有实验数据基础上,对其进行系统学研究在核能应用以及核裂变现象 The neutron fission cross section of actinides is an important nuclear data in nuclear reactors and nuclear engineering design. So far, although a certain amount of experimental data on fission cross sections have been obtained, some of them are still lacking due to the difficulty of obtaining samples or experimental conditions. Therefore, based on the existing experimental data, it is systematically studied in nuclear energy applications and nuclear fission
