【摘要】 本文介绍了一台配有多系正比室的透射式穆斯堡尔谱仪,它特别适用于样品的快速分析,从而有利于测量精度的提高.文章叙述了多系正比室结构、原理,给出了室性能的测量结果.它对穆斯堡尔源放射的14.4Kev γ射线有较好的能量分辨率和较高的探测效率,特别具有较高的计数率响应,最高计数率可达2×10~6cps,最后,给出了该谱仪的穆斯堡尔谱.更多还原

【Abstract】 In this paper the m(?)ssbauer spectroscopy of transmission type with muitiwireproportional chambers is detailed.It is especially suitable for rapid analysis ofsamples,and so is advantageous to raising the precision of measurement.Theconstruction,principle and characteristics of multiwire proportional chambers arepresented.The chambers have better energy resolution,higher detecting efficiencyand higher counting rate capability of up to 2×10~6 cps in the 14.4 Kev energyregion.This paper has given the m(?)ssbauer spectrum to the spectroscopy withMWPC.更多还原
