Carbon-11 exists as a radioactive isotope of carbon that decomposes to boron-11. This decay primarily happens due to positron emission, with around 0.19–0.23% of decays instead happening by electron capture. It includes a half-life of 20.3402(53) min.
Positron emission, beta plus decay, or β+ decay exists a subtype of radioactive decay named beta decay, in which a proton inside a radionuclide nucleus exists converted into a neutron while emitting a positron and an electron neutrino (νe). Positron emission exists mediated by a weak force.
