中子截面
中子吸收截面
Examples
- Adopting single pulse neutron exposure 22ne ( a , n ) 2dmg and the updated neutron cross section , making use of the core helium burning model of the single neutron exposure theory , we calculate the s - process nucleosynthesis in massive stars at different mettalicity and compare the results with the solar s - weak component
我们采用单脉冲中子源‘ zne （ a ， n ） zsmg ，采用最新发表的中子俘获截面，用中心氦燃烧模型计算了各金属丰度情况下15m m叼0m 。的大质量星的s过程核合成，并将所得结果与太阳的s刁分量进行比较。 - Mastering the output format of covariance of neutron cross section in endf / b - 6 evaluated nuclear data library , clearly understanding the meaning of each physical quantity , grasping the mathematical methods pf covariance for experimental nuclear data and evaluated nuclear data , a set of evaluation processing method was deduced from the meaning of cross sections and errors . and then a program was developed for evaluating and processing the covariance matrix of experimental data , which are output in the endf / b - 6 format
在熟悉endf / b - 6评价中子核数据库协方差文档的格式要求，确定各个量的物理意义，并掌握实验和评价数据的协方差数学处理方法的基础上，由截面数据及截面误差的物理意义，推出了一套合适的评价处理方法，最后编写了按endf / b - 6格式输出的协方差数据评价处理程序，作为中国评价中子核数据库( cendl )协方差文档的数据输出程序。
