摘要

根据金热中子捕获截面对NBS热中子通量进行了校准。1961年9月，热中子(低于镉的截止能量)的有效通量密度估计为4307±2% n/cm2秒。这一数字与国家统计局最近公布的数据一致。

An Absolute Calibration of the National Bureau of Standards Thermal Neutron Flux

The NBS Thermal Neutron Flux has been calibrated in terms of the gold thermal neutron capture cross section. The effective thermal neutron (below cadmium cutoff energy) flux density is estimated to be 4307 ± 2 percent n/cm2 sec in September 1961. This figure is in agreement with a recent value quoted by the NBS.
