在核数据评价中,各种反应末态为分立能级的反应截面和角分布是重要的数据,而角分布又是反映反应机制变化的一种灵敏信息。大多数情况是对不多的能点和少数角度进行测量,因此,上述实验数据有很多空缺,需进行理论计算增补。在核数据的模型计算中,需要有关相互碰撞粒子对（入射粒子和靶核）及各种可能反应道之相应剩余核低激发反应末态的详细资料,包括入射粒子和靶核,各种可能的出射粒子和剩余核的基态自旋和宇称,各种剩
In the nuclear data evaluation, the reaction cross section and angular distribution of various final states of reaction are important data, and the angular distribution is also a sensitive information reflecting the change of reaction mechanism. In most cases, measurement is possible on a small number of energy points and few angles. Therefore, there are many vacancies in the above experimental data and need to be theoretically calculated and supplemented. In the modeling of nuclear data, detailed information on the final state of the low-activation reaction of the corresponding remaining nuclei of the colliding particle pairs (incident particles and target nuclei) and of the various possible reaction channels, including incident particles and target nuclei, and various possibilities The exiting particles and the remaining nuclei of the ground state spin and parity, all sorts of remnants
