Collisions Involving Positrons and Positronium

摘要：

In this talk I shall look at theoretical aspects of positron and positronium collisions with atoms Because of the competition between the positron and the atomic nucleus for electrons, positron-atom scattering is inherently a two-centre process, in contrast to electron-atom scattering where the whole dynamics is essentially centred on the atomic nucleus. It is this two-centre nature which makes the theoretical description of positron-atom scattering so much more difficult than that of electron-atom scattering.
