摘要
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 constants from beta decay electrons are found not to be significantly different from recoil electrons from Compton scattering and thus do not account for the anomalous shorter pulses.
