Question: what is the difference between beta minus and beta plus decay?
Answer: In beta minus decay, a neutron decays into a proton, an electron, and an antineutrino: n Æ p + e - +. In beta plus decay, a proton decays into a neutron, a positron, and a neutrino: p Æ n + e+ +n. ... However within a nucleus, the beta decay process can change a proton to a neutron.
