... This process occur with neutron deficient or proton rich nuclei. Conversion of a proton into neutron + positron (β+ ) + v (neutrino). Positrons are emitted with a continuous energy spectrum. After β+ particle emission, the daughter nuclide has an atomic number that is one less than that of t ...
