摘要
中子能谱是中子辐射场的基本参数之一，也是确定中子比释动能和中子吸收剂量所必需的物理参量。本文介绍一种用步长加速法求解活化法测量的中子能谱的方法。该方法编程简单，可在各类微机上进行计算，使用４８６微机十几分钟就能获得结果。与ＳＡＮＤⅡ计算程序的计算结果相比，在实验误差范围内一致。
Neutron energy sepectrum is one of basic parameters of neutron radiation field and is also a necessary physics parameter in estimating neutron kerma and neutron absorber dose. This paper discribes a partten search method of nonlinear programing to find the solution of neutron energy spectrum of activation measured method. This method is simple in programing and can be used in all kinds of personal computers. A spectrum analysis needs only about minutes at IBM 486 computer. The result is agreed with computed result of SAND Ⅱ programme within experimental error range. (
