| 摘 要： | 对不同厚度的样品,分别采用无限大平板和圆柱体模型,用Monte-Carlo方法计算中子多次散射修正.结果表明,对于慢中子,当样品半径与厚度之比大于20,使用无限大平板模型并进行半解析处理具有明显的优越性.辅以其它技巧,把这方法用于多种实验截面的中子共振参数的相关面积分析中得到满意的结果. |

| Abstract: | Both infinite slab model and cylinder model with various sample thicknesses have been used to calculate the corrections of the neutron multiscattering by the Monte-Carlo procedure. The results show that, if the radius-to-thickness ratio of the sample is greater than 20, the infinite slab model with semi-analytical treatment is obviously advantageous for slow neutrons. Being combined with some other auxiliary techniques, this mothed has been applied to the correlation area analysis of neutron resonance for various experimental cross sections, and the results obtained are satisfactory. |
