Single, double, and triple Auger decay of the Xe4pcore-hole states

Auger decay paths of mercury5pand4fvacancies revealed by multielectron spectroscopy

“…By im plem enting electron-electron coincidence techniques, the decay pathw ays can be resolved state by state. Several coincidence experim ents appeared in the last decades (see, for exam ple, [1][2][3][4][5][6][7][8][9][10]) and have proven their ability to disentangle the com plexity o f A uger spectra. In electron-electron coincidence experim ents the photoelectron and one o r several A uger electrons are detected together.…”

CDW-EIS calculations for multiple ionization of Ne, Ar, Kr and Xe by the impact of H+and He+, including post-collisional electron emission

“…The advent of attosecond physics caused time evolution of Auger relaxation processes in atoms and solids to attract increasing attention [15][16][17]. New measurements have been performed in the last 20 years using synchrotron radiation together with time-of-flight spectroscopy and coincidence techniques [18][19][20][21][22][23][24][25][26][27][28][29][30][31] . In this work we review photoionization branching ratios from the pioneering works by Carlson, Krause and co-workers [2][3][4][5][6][7] up to the present.…”

Triple ionization spectra by coincidence measurements of double Auger decay: The case of OCS

“…In double Auger, by contrast, the two Auger electrons share the available excess energy, dividing it between them with a distribution, which is in principle unknown. Recent coincidence studies of the double Auger effect in atoms [2][3][4][5] have shown that both "direct" and "cascade" pathways exist, giving continuous and discrete electron distributions, respectively. Cascade pathways involve the formation of intermediate doubly ionized states with quantized energies and measurable widths ͑lifetimes͒.…”
