扩展能量范围内$^{125}$ I的定量电子能谱
Quantitative electron spectroscopy of $^{125}$I over an extended energy range
摘要：
核衰变后发射的俄歇电子在肿瘤靶向治疗中具有潜在的应用价值。为此，了解每核衰变的俄歇电子产额是很重要的。在这项工作中，我们测量的转换电子（发射的核衰变过程的一部分）和俄歇电子（发射的核衰变后的原子弛豫过程的一部分）的情况下，$^{125}$ I的数量的比率。结果进行了比较与蒙特卡罗型模拟的弛豫级联使用BrIccEmis代码。通过适当选择参数，该程序在整个能量范围内很好地描述了所观察到的光谱。
英文摘要：
Auger electrons emitted after nuclear decay have potential application in targeted cancer therapy. For this purpose it is important to know the Auger electron yield per nuclear decay. In this work we measure the ratio of the number of conversion electrons (emitted as part of the nuclear decay process) and the number of Auger electrons (emitted as part of the atomic relaxation process after the nuclear decay) for the case of $^{125}$I. Results are compared with Monte-Carlo type simulations of the relaxation cascade using the BrIccEmis code. With the appropriate choice of parameters this program describes the observed spectra quite well over the whole energy range.
