alpha decay
beta decay
gamma decay
positron decay

GPT-5 mini · Answer

Gamma decay.

Gamma decay is the emission of high-energy photons (gamma rays) when a nucleus drops from an excited state to a lower-energy state. (Other decays—alpha, beta, positron—emit particles; they can also be followed by gamma emission if the daughter nucleus is left excited.)
