This item was taken from the IEEE Periodical ' Nonproportionality of Scintillator Detectors: Theory and Experiment. II ' We report measurements of electron response of scintillators, including data on 29 halides, oxides, organics, and fluorides. We model the data based on combining the theories of: Onsager, to account for formation of excitons and excited activators; Birks, to allow for exciton-exciton annihilation; Bethe-Bloch, to relate electron stopping to its energy; and Landau, to describe how fluctuations in the linear energy deposited (dE/dx) lead to nonproportionality's contribution to resolution. In general there is satisfactory agreement with experiment, in terms of fitting the electron response data and reproducing the literature values of resolution. We find that the electron response curve shapes are more affected by the host lattice than by the activator or its concentration.
