Physical properties of the positron and the positronium atom In Dirac's theory it was shown that an electron and a positron can annihilate together. Dirac visualized this behaviour of an electron-positron system by saying that an electron with positive energy may fall down in a hole in the "negative energy electron states".

In a way, positronium formation effects replace the exchange effects encountered in electron scattering. However, positron-electron correlations are generally much
Web23 mei 2024 · The positronium is a neutral atomic system consisting of an e +e − pair, where the positron e + is the antiparticle of the electron. Here we study the energy levels of this system, in particular the hyperfine splitting of its ground state. We also investigate the decay of positronium due e + − e − annihilation.
