Beta Decay
Beta-minus decay: a neutron converts to a proton, emitting an electron and antineutrino. This increases the atomic number by 1 while keeping mass number constant.
Variables
nunitless
Neutron
punitless
Proton
e^-unitless
Electron (beta particle)
\bar{\nu}_eunitless
Electron antineutrino
Derivation
Mediated by the weak nuclear force through W boson exchange.
