Question: what is the difference between beta plus and beta minus 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. ... A neutron in a nucleus will decay if a more stable nucleus results; the half-life of the decay depends on the isotope.
