POSITRON IMPACT PHENOMENA

Atomic collision experiments using low-energy positron beams have been actively pursued for more than two decades. With greater understanding of the basic physics governing the production of these beams, advances in technology have promoted studies beyond measurements of total collision cross sections. Such work forms the basis of this review and includes topics from elastic scattering, positronium formation and the associated production of positronium beams, excitation, ionisation and attachment. © 1990 Elsevier Science Publishing Co., Inc.
