The degree of electron itinerancy and shell closing in the core ionized state of transition metals probed by Auger photoelectron coincidence spectroscopy
Autor: Artur Born, Fredrik O. L. Johansson, Torsten Leitner, Ieva Bidermane, Danilo Kühn, Nils Mårtensson, Alexander Föhlisch
Auger photoelectron coincidence spectroscopy APECS has been used to examine the electron correlation and itinerance effects in transition metals Cu, Ni and Co. It is shown that the LVV Auger, in coincidence with 2p photoelectrons, spectra can be repr

The CoESCA station at BESSY: Auger electron–photoelectron coincidences from surfaces demonstrated for Ag MNN
Autor: Ieva Bidermane, Torsten Leitner, Frank O. Schumann, Artur Born, Ruslan Ovsyannikov, Alexander Föhlisch, Nils Mårtensson, Svante Svensson, Yasmine Sassa, Andreas Lindblad, Fredrik Johansson
Publikováno v: Journal of Electron Spectroscopy and Related Phenomena
In this work, we present the CoESCA station for electron-electron coincidence spectroscopy from surfaces, built in a close collaboration between Uppsala University and Helmholtz-Zentrum Berlin at the BESSY II synchrotron facility in Berlin, Germany.

Autor: Svante Svensson, Artur Born, Torsten Leitner, Ruslan Ovsyannikov, Nils Mårtensson, Ieva Bidermane, Alexander Föhlisch
Publikováno v: Physical Review B. 103
Ni $LVV$ Auger spectra, in coincidence with the corresponding $2{p}_{1/2}$, $2{p}_{3/2}$, and $6\phantom{\rule{0.28em}{0ex}}\text{eV}$ satellite photoelectrons, have been used to examine electron correlation and itinerance effects in Ni. In coinciden
