H. Ast et al., ELECTRON-IMPACT IONIZATION OF THE K-SHELL OF SILVER AND GOLD IN COPLANAR ASYMMETRIC GEOMETRY, Physical review. A, 50(1), 1994, pp. 180000001-180000003
Triple differential cross sections are presented for the electron-impa
ct ionization of silver and gold in coplanar asymmetric geometry at an
impact energy of 500 keV. The problem is treated in a completely rela
tivistic manner, using Dirac distorted waves in both the incident and
final channels and the full photon propagator. Good agreement with exp
eriment is obtained.
