摘要
本文介绍由单能级Breit-Wigner共振参数并应用复概率积分法对多普勒展宽截面进行计算的步骤,并以^(239)Pu为实例作了说明。与其他数值方法比较,在同样精度下,PDP11/70计算机上用复概率积分的计算时间比用其他方法约少50倍。
Calculation of Doppler broadening cross-sections from the single-level Breit-Wigner resonance parameters is presented by using the complex probability integral method. An example for 239Pu is given. The calculation time using this method at PDF 11/70 computer is about 50 times less than that using other numerical methods with the same accuracy.
