用9-100 keV的高单色同步辐射测量了NaI：Tl闪烁产额的非比例响应。特别注意的是X射线逃逸峰。它们为我们提供了关于0.9-12 keV范围内的光子响应的额外信息。在碘K-电子结合能附近观察到光子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。
Nonproportional response of the scintillation yield of NaI:Tl was measured using highly monochromatic synchrotron irradiation ranging from 9–100 keV. Special attention is paid to the x-ray escape peaks. They provide us additional information about photon response in the range 0.9–12 keV. A rapid variation in the photon 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.
