| 摘 要： | 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.
