摘要：

The elastic differential cross sections of electrons scattered from one- and two-electron multiply charged ions are calculated within the first-order distorted-wave approximation. The exchange amplitude is found to be important for scattering at large angles. The results are compared with previous calculations and with experimental differential cross sections at 180-degrees derived from analysing the binary-encounter electron spectrum from the collision of 19-30 MeV F7+ and F8+ ions with H-2 and He targets.
