Meaning of beta.
In physics, beta refers to the beta decay process and beta particles. Beta decay is a type of radioactive decay in which a nucleus emits a beta particle, which can be either an electron or a positron. Beta decay occurs when there is an excess of neutrons or protons in the nucleus, causing it to become unstable.
