  • Abstract
    This paper is the third in a series of articles on the basic physics of nonproportionality in scintillators. Here, we focus on the temperature dependence of six scintillators, NaI(Tl), CsI(Tl), CsI(Na), CeBr3, LaBr3(Ce), and undoped SrI2, and report their nonproportionality curves at -40°C, 0°C and + 40°C. We fit the data to a modified form of our previously employed model, including the competition of carrier trapping with the Onsager-mediated attraction between electrons and holes.
