中子和带电粒子核反应数据的评价中的一个重要的发展趋势是核反应理论计算程序的应用,以获取许多应用需要的人量的各种截面、角分布、能谱等方面的数据。 理论计算作为一种评价方法具有很多优点: 1）它可给出任意入射能量、出射能量及出射角的反应数据,不受实验条件的限制; 2）理论计算结果是自洽的,而不同实验室测量的分截面和总截面或反应截面之间经常 不自洽: 3）理论计算是唯一能够预言数据的方法。
An important trend in the evaluation of neutron and charged particle nuclear reaction data is the application of nuclear reaction theory calculation programs to obtain data on various cross sections, angular distributions and energy spectra for many applications. Theoretical calculation as an evaluation method has many advantages: 1) It can give the reaction data of any incident energy, exit energy and exit angle, without being limited by the experimental conditions; 2) The theoretical calculation results are self-consistent, while different experiments Often, the measured cross-sectional area and total cross-section or reaction cross-section are not self-consistent: 3) Theoretical calculations are the only way to predict the data.
