Abstract
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.
