S. Ricz, ANGULAR-DEPENDENCE OF POSTCOLLISION INTERACTIONS, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 86(1-2), 1994, pp. 119-126
The angular dependence of post collision interaction is reviewed, conc
entrating on fast ion atom collisions when the velocity of the project
ile approximately equals that of the ejected Auger electron. Whereas e
xisting theories can explain the measured line distortion and energy s
hift in the forward direction, the observed enhancement of satellite t
o diagram KLL ratios cannot be reproduced, thus necessitating further
experimental and theoretical studies.
