TLDR
A theoretical model is proposed providing absolute photoionization cross sections and revealing clear signatures of direct (monopolar) and conjugate (dipolar near-edge x-ray absorption fine structure) shakeup lines of comparable magnitude.Abstract:
Simultaneous core ionization and core excitation have been observed in the C(2)H(2n) (n=1, 2, 3) molecular series using synchrotron radiation and a magnetic bottle time-of-flight electron spectrometer. Rich satellite patterns corresponding to (K(-2)V) core excited states of the K(-1) molecular ions have been identified by detecting in coincidence the photoelectron with the two Auger electrons resulting from the double core hole relaxation. A theoretical model is proposed providing absolute photoionization cross sections and revealing clear signatures of direct (monopolar) and conjugate (dipolar near-edge x-ray absorption fine structure) shakeup lines of comparable magnitude.read more

TL;DR: A theoretical model that provides absolute cross sections for simultaneous core-ionization core-excitation (K(-2)V) and its predictions with experimental results obtained on the water molecule after photoionization by synchrotron radiation are compared.

TL;DR: In this article, the authors give an outlook on the basis of recently published results, of the complementarity of these light sources for double core-hole spectroscopy, with a prospective of what could be done in the future with the technical breakthrough that will be necessary to improve our further understanding of chemical analysis.

TL;DR: The formalism developed in the companion Paper I is used here for the interpretation of spectra obtained recently on the nitrogen molecule, and the evolution with photon energy of the relative contribution of shake- up and conjugate shake-up processes is discussed.
