A study of the Ne 2s2p5(3P)3s and 3p correlation satellites up to 75 eV above threshold

Abstract

The 2s2p5(3P)3s 2P, 3p 2D and 2S satellite states of neon have been studied at several energies from 5 to 75 eV above their respective thresholds. The relative intensities of the satellite states with respect to their main lines shed light on the nature of the many-electron correlations leading to the formation of these satellites. The experimental results are compared with a calculation which makes use of a random phase approximation with exchange (RPAE) cross sections, and takes into account the shake-up and direct knock-out channels as well as their interference.
