Using a LaBr_3:Ce scintillator for positron annihilation lifetime spectroscopy
《Chinese Physics C》2012年第4期380-383,共4页刘军辉 李道武 章志明 王宝义 张天保 郝佳 魏龙 
Supported by National Natural Science Foundation of China(10805049,10775149)
A LaBr3:Ce scintillator has a high light output (~60000 p.e/MeV) and a short decay constant (25 ns), which makes it good for time spectrometry. Compared with a BaF2 scintillator, it can bear a much higher count ...
