Abstract Using the optical-model, we theoretically investigate the positronium (Ps) formation in e⁺--Mg collision from the positronium threshold to 60.0eV. A complex equivalent local polarization potential is obtained to describe the rearrangement process, which reproduces Ps formation cross section. We report the total Ps (n=1+2) formation cross sections and compare them with the experimental measurements and other theoretical results.
