Positronium (Ps) is a bound state of an electron and a positron. Ps scattering from atoms and molecules has interesting similarities to that of electron scattering from atoms and molecules. A charge-transfer reaction between Ps and an antiproton can generate antihydrogen which is important for experiments that test the fundamental symmetry laws of our universe. We perform inelastic Ps scattering calculations with different targets in order to explain experimental results and provide theoretical estimates for antiydrogen experiments
