This process sees no change in the mass number of the atom involved, but it does see a change in the atomic number.
The double form of this process can be used to experimentally search for a Majorana particle. Cobalt-60 underwent this process in an experiment which confirmed parity violation that was performed by Wu. This process is caused by the weak force acting on a single quark, and it sees the emission of a neutrino or antineutrino. This process sees no change in the mass number of the atom involved, but it does see a change in the atomic number. For 10 points, name this type of decay which sees the emission of an electron or a positron and is contrasted with another type of decay that sees the emission of an alpha particle.
The double form of this process can be used to experimentally search for a Majorana particle.
