12Radioactive decay — For particle decay in a more general context, see Particle decay. For more information on hazards of various kinds of radiation from decay, see Ionizing radiation. Radioactive redirects here. For other uses, see Radioactive (disambiguation).… …
13beta decay — Physics. a radioactive process in which a beta particle is emitted from the nucleus of an atom, raising the atomic number of the atom by one if the particle is negatively charged, lowering it by one if positively charged. [1930 35] * * * Any of… …

15Double beta decay — is a radioactive decay process where a nucleus releases two beta rays as a single process. In double beta decay, two neutrons in the nucleus are converted to protons, and two electrons and two electron antineutrinos are emitted. In the process of …
16gamma decay — Type of radioactivity in the most common form of which an unstable atomic nucleus dissipates energy by gamma emission, producing gamma rays. Gamma decay also includes two other processes, internal conversion and internal pair production. In… …
17Proton emission — (also known as proton radioactivity) is a type of radioactive decay in which a proton is ejected from a nucleus. The decay of a proton rich nucleus A populates excited states of a daughter nucleus B by β+ emission or electron capture (EC). Those… …

19beta decay — n. radioactive disintegration of a nucleus with the accompanying emission of a beta particle: the residual nucleus has one more unit of positive charge after electron emission and one less after positron emission …
20Particle decay — is the spontaneous process of one elementary particle transforming into other elementary particles. During this process, an elementary particle becomes a different particle with less mass and an intermediate particle such as W boson in muon decay …
