Cathodoluminescence (CL), the emission of light induced by accelerated free electrons, has been extensively utilized in various applications, such as displays, streak cameras, and high-spatial-resolution analysis optical material, surpassing diffraction limit light. Despite its long history, photon statistics CL have only recently examined, revealing unexpectedly large bunching photons. Here we find that this peculiar contains information intervening excitation processes before emission, which can be extracted from within each event a single electron. Using approach, experimentally unveiled statistical differences coherent involving electromagnetic interaction process incoherent multiple processes. The developed formulation is universally applicable for particle generation general to investigate nature cascade reactions.
