摘要：
Formation of positronium (Ps) atoms in collisions of fast positrons impacting on atoms (ions) is studied. Total cross sections (TCSs) for hydrogen targets obtained with several theoretical approximations are compared. Scaling laws for hydrogenic targets are given, The TCSs for potassium targets are computed and comparison with other theories and experiments is made. (C) 1997 Elsevier Science B.V.
