摘要
文章叙述了14MeV中子反应截面综合评价的基本思想及数学处理方法。对^(56)Fe(n,p)^(56)Mn,^(27)Al(n,α)^(24)Na,^(63)Cu(n,2n)^(62)Cu,^(27)Al(n,p)^(27)Mg和^(41)K(n,p)^(41)Ar等五种反应截面进行综合评价,得到了较满意的结果。评价值分别为109.7,114.2,533.5,71.8和48.0mb,误差(1σ)分别为0.88%,1.1%,1.5%,2.6%和3.2%。
The main idea and mathematical treatment of the simultaneous evaluation of14 MeV neutron cross section are described in detail. A simultaneous evaluationof the ^(56)Fe(n, p) ^(56)Mn, ^(27)Al(n, a)^(24)Na, ^(63)Cu(n, 2 n)^(62)Cu, ^(27)Al(n, p)^(27)Mg, ^(41)K(n, p)^(41)Ar cross sections is done and yielded a set of considerably satisfying resultswhich are 109.7, 114.2, 533.5, 71. 8 and 48. 0 mb, with errors (1 σ) 0.88%, 1. 1%,1.5%, 2.0% and 3.2% respectively.
