Abstract
The scintillation pulse shape in NaI crystals of electrons from beta decay is investigated, as a possible explanation of anomalous pulses seen in dark matter searches based on NaI detectors. The pulse shapes and time constant s from beta decay electrons are found not to be significantly different fro m recoil electrons from Compton scattering and thus do not account for the anomalous shorter pulses.
