探测中子有许多方法,其中不少是很准确的,但一般说来,设备较复杂,技术上较难,不合简易之要求。而其中激活法是应用很广泛的简易探测中子的方法。我们应用激活化,间接地探测中子,在这方面获得了初步的结果。由于我们所采用的方法与文献记载有不少出入,故在这里也对某些问题作了初步的探讨。一、激活法探测中子的基本原理。慢化了的电子被稳定核吸收,往往生成放射性的核,这可以用来探测中子,如果中子 There are many ways to detect neutrons, many of them are very accurate, but in general, the equipment is more complex, technically difficult, substandard requirements. Among them, the activation method is a very simple method of detecting neutrons. We apply the activation, indirect detection of neutrons, in this regard obtained preliminary results. Due to the method we used and the literature there is a lot of discrepancies, so here are some of the issues made a preliminary discussion. First, the activation of the basic principles of neutron detection. Moderated electrons are absorbed by the stable nuclei, often generating radioactive nuclei, which can be used to detect neutrons if neutrons
