摘要:

NaI:Tl的闪烁产率的非比例响应测量使用高度单色同步辐射范围从9到100 keV。特别注意的是X射线逃逸峰。他们为我们提供了额外的信息,在0.9至12千电子伏的范围内的非比例响应。在碘K-电子结合能附近观察到非比例响应曲线的快速变化。围绕这个能量进行密集的数据采样,这些数据用于应用一种方法,我们称之为K-浸渍光谱法。这种方法使我们能够得到的电子响应曲线的NaI:Tl低至30 eV的能量。我们的数据与其他采用不同方法的数据进行了比较。所提出的技术和方法的优点,局限性和特点进行了讨论。

英文摘要:

Non-proportional response of the scintillation yield of NaI:Tl was measured using highly monochromatic synchrotron irradiation ranging from 9 to 100 keV. Special attention is paid to the X-ray escape peaks. They provide us additional information about non-proportional response in the range 0.9 to 12 keV. A rapid variation of the non-proportional response curve is observed near the Iodine K-electron binding energy. A dense sampling of data is performed around this energy and that data are used to apply a method, which we call K-dip spectroscopy. This method allows us to derive the electron response curve of NaI:Tl down to energies as low as 30 eV. A comparison of our data with data of others employing different methods is made. Advantages, limitations and peculiarities of presented techniques and methods are discussed.
