研究了NaI（Tl）在6 keV ~ 1 MeV能量范围内对电子的相对响应。6 keV的光输出对暴露表面的性质非常敏感。结果给出了两个最好的切割碘化钠（铊）晶体和比较从光子数据推导出的电子响应。有很好的协议高于20千电子伏，在表面条件的变化几乎没有敏感性观察。对蒽和Pilot B进行类似的测量。显示了所有三种发光器的每单位能量的相对光输出。它们作为低能电子探测器的优点被发现受到背散射量以及电离事件所产生的长寿命激发态的强度和持续时间的显着影响。
An investigation was made of the relative response of NaI(Tl) to electrons over an energy range of 6 keV to 1 MeV. The light output at 6 keV is quite sensitive to the nature of the exposed surface. The results are given for the two best cleaved NaI(Tl) crystals and compared to the electron response deduced from photon data. There is good agreement above 20 keV, where little sensitivity to changes in surface condition was observed. Similar measurements were made for anthracene and Pilot B. The relative light output per unit energy is shown for all three scintillators. Their merit as low energy electron detectors was found to be significantly affected by the amount of backscattering and the intensity and duration of long lived excitation states arising from ionizing events.
