The photon and electron spectra of 158*Gd as result of the (n, gamma)-reaction on 157Gd were calculated with IMRDEC Monte Carlo computer program. The relaxation probabilities were taken from EADL file of the Lawrence Livermore National Laboratory. Because this file does not consist of data for some N and O transitions, they were additionally determined by Chen applying the DHS j-j scheme. Two schemes are applied to calculate the energies of the transitions: (1) a simple (Z + 1)/Z scheme, and (2) accurate calculation solving the relativistic Dirac equations.
利用IMRDEC蒙特卡罗计算机程序计算了157Gd上(n,γ)反应产生的158*Gd的光子和电子能谱。弛豫概率取自劳伦斯利弗莫尔国家实验室的EADL文件。由于该文件不包含某些N和O跃迁的数据，陈采用DHS j-j方案对其进行了补充测定。应用两种方案来计算跃迁能量：(1) 简单的(Z + 1)/Z方案，(2) 求解相对论狄拉克方程的精确计算。
