As in the case of electrons, various interactions of positrons with atom, ions, molecules, and radiation are possible. There is no exchange between electrons and positrons. However, during scattering of positrons from targets, there is a possibility of annihilation of positrons with electrons giving a 511 keV line, which has been seen from the galactic center and in solar flares. There is also a possibility of positronium formation, Resonance parameters of odd and even parities in Ps ions have been calculated and the lowest odd-parity resonance has been observed using two different laser wavelengths. Photo-detachment of Ps ions can be used to create Ps beams. Resonance parameters in positron-hydrogen system have been calculated.
