U. Arp et al., ANGULAR-CORRELATION BETWEEN K-ALPHA PHOTONS AND L(2,3)-M(2,3)M(2,3) AUGER ELECTRONS FOLLOWING ARGON 1S PHOTOIONIZATION, Journal of physics. B, Atomic molecular and optical physics, 29(23), 1996, pp. 837-842
An analysis is presented of the angular correlation between KCL fluore
scence photons and subsequently emitted L(2,3)-M(2,3)M(2,3) Auger elec
trons following K-shell ionization. The relative intensities of the Au
ger lines change in the coincidence experiment compared to the normal
L(2,3)-M(2,3)M(2,3) Auger lines measured after direct 2p photoionizati
on. A theoretical model is introduced to account for angular correlati
on effects and applied to reproduce experimental findings.
