翻译后摘要：多箔活化迭代方法已被开发，以确定中子通量谱。一个计算机代码（SAND II）已被写入，它提供了一个“最佳拟合”的中子微分通量谱为一个给定的输入无限稀释箔活动。对各种中子环境的实验和分析研究结果表明，除了确定中子通量谱外，多箔活化迭代法还有助于：（1）验证和改进用于预测通量谱的计算技术;（3）确定箔放射性测量方法的可靠性;（4）评估材料散射/吸收效应;以及（5）检查当前箔探测器横截面评估以提供对这些数据的重新评估的指导，以及对于产生可检测产物的任何箔反应，截面的绝对微分形式的最终“展开”。
Abstract : A multiple foil activation iterative method has been developed to determine neutron flux spectra. A computer code (SAND II) has been written which provides a 'best fit' neutron differential flux spectrum for a given input set of infinitely dilute foil activities. The results of experimental and analytical studies for a wide variety of neutron environments strongly suggest that, in addition to determining neutron flux spectra, the multiple foil activation iterative method can be helpful in (1) the validation and improvement of calculational techniques used to predict flux spectra; (2) upgrading of confidence in neutron spectrometer measurements; (3) determining the reliability of foil activity measurements methods; (4) assessing material scattering/ absorption effects; and (5) examining current foil detector cross section evaluations to provide guidance for re-evaluation for these data, and eventual 'unfolding' of the absolute differential form of cross sections for any foil reactions producing a detectable product.
