PPT-Examples of Positron decay:

Alpha Decay Alpha decay occurs for those nuclides which have an atomic number greater than 82 Such heavy nuclides have no stable configuration of neutrons and protons and as a result emit an alpha particle consisting of 2 protons and 2 neutrons. Positron Sources Positrons can be obtained from the b of radioactive isotopes, e.g. from 22Na according to the decay reaction 22Na Roberta Sparvoli. Rome . “. Tor Vergata. ”. . University. and .
