混合惰性气体中~ 3 He（n，tp）反应的远紫外特征
Far-ultraviolet signatures of the 3He(n,tp) reaction in noble gas mixtures
摘要：
以前的工作表明，在大气压下，在3 He电池中的3 He（n，tp）反应产生了数十个远紫外光子，每个反应中子。在这里，我们报告放大的信号的因素1000和更多的惰性气体时，加入到细胞。经校准的滤波器-检测器测量表明，这种大信号是由于稀有气体受激准分子发射，并且核反应能量以高达30%的效率转化为远紫外辐射。通过在NIST SURF III同步加速器上进行校准，将结果置于绝对尺度上。他们提出了高效中子探测器作为现有正比计数器替代品的可能性。
英文摘要：
Previous work showed that the 3He(n,tp) reaction in a cell of 3He at atmospheric pressure generated tens of far-ultraviolet photons per reacted neutron. Here we report amplification of that signal by factors of 1000 and more when noble gases are added to the cell. Calibrated filter-detector measurements show that this large signal is due to noble-gas excimer emissions, and that the nuclear reaction energy is converted to far-ultraviolet radiation with efficiencies of up to 30%. The results have been placed on an absolute scale through calibrations at the NIST SURF III synchrotron. They suggest possibilities for high-efficiency neutron detectors as an alternative to existing proportional counters.
