This process does not change the mass of the atom undergoing it, though it does change the atomic number by one.
A cubic array of cadmium-zinc-telluride crystal detectors are being used to study one form of this process in the COBRA experiment and that form of this process is also trying to be detected by the Enriched Xenon Observatory. The energy spectrum from this process can be plotted on the x-axis against the square root of the number of particles involved and this construction is known as a(*) Kurie plot. The violation of parity for the weak force was discovered by observing this process in a 1956 experiment by Wu. The "double" version of this process can occur without a neutrino if the neutrino is its own antiparticle and this form is exhibited by uranium-238. This process does not change the mass of the atom undergoing it, though it does change the atomic number by one. For 10 points, identify this radioactive process which emits a positron or electron.
