Beta particle spectroscopy is and interesting and curious phenomenon, because unlike alpha particles or gamma particles, betas do not have a set energy. The energy is distributed between three particles upon decay. With my equipment I am able to analyze this distribution and determine the maximum possible energy these particles can have and in doing so determine the most likely. Now while that’s tricky enough sometimes internal conversion peaks appear in the spectrum and that is where it gets interesting. Internal conversion is caused by gamma particles giving their energy to an electron, which is then picked up by the detector.
