Aerospace | Radioactive transformation of a nuclide in which the atomic number changes by ±1 with the emission of a beta particle and the mass number remains unchanged. Also called beta disintegration .Increase of atomic number occurs with negative beta particle emission, decrease with positive beta particle (positron) emission or upon electron capture.

Beta decay is a type of radioactive decay in which a beta particle (an electron or a positron) is emitted. In the case of electron emission, it is referred to as "beta minus"(β- ), in the case of a positron, "beta plus"(β+ ).
In beta minus decay, a neutron is converted to a proton via the weak nuclear force and a beta particle (an electron) and an anti-neutrino are emitted.
In beta plus decay, a proton is converted to a neutron via the weak nuclear force and a beta minus particle (a positron) and a neutrino are emitted.
The study of beta decay provided the first physical evidence of the neutrino. The energies of electrons emitted by beta decay were observed to be non-continuous (some being more energetic than others). A problem arose in trying to explain what happened to the missing energy if an electron was emitted with less than maximum energy - the Law of conservation of energy appeared to be violated. To solve this, Wolfgang Pauli proposed that the "missing" energy was carried away by another yet undiscovered particle - the neutrino. This was analysed in more detail by Enrico Fermi.
