H. Kjeldsen et al., POSTCOLLISION INTERACTION EFFECTS IN NEAR-THRESHOLD AR L(2)-SHELL PHOTOIONIZATION, Journal of physics. B, Atomic molecular and optical physics, 29(9), 1996, pp. 1689-1698
Near-threshold photoionization of argon in the L(2) (2p(-1) P-2(1/2))
inner-shell region has been studied by means of threshold photoelectro
n-photoion coincidence spectroscopy. The observed line profiles are cl
early influenced by the post-collision interaction effect and this inf
luence is observed to be stronger for double than for single-Auger dec
ay. The spectra have been interpreted using a classical theory which t
akes into account the possibility that a single photoelectron can inte
ract with several Anger electrons.
