Abstract

Corrections to the independent electron approximation in atomic scattering incorporate correlation. At very high collision velocities, correlation often dominates for multiple electron transitions. Generalized shake probabilities depend on correlation in static asymptotic wavefunctions. Various shake contributions are considered including shakeoff, shakeup, and shakeover. Some overall scalling relations of these shake probabilities with target and projectile charges and collision velocities is discussed. A distinction between shake and two-step electron-electron collision mechanisms is made. Recent observations indicating that shake-off probabilities are dependent on projectile parameters is discussed. Further experimental and theoretical studies are recommended.
