“…1͑c͒ the sum of the two partial Auger spectra, both for the experimental and theoretical results, is compared with the noncoincidence one measured simultaneously. 31 Thus it is not unlikely that decay to N 2 O + may occur. 22 The theoretical simulation reproduces the summed coincidence experiment very well, both in the shape and the relative intensity of the three main features.…”

The N 1s Auger spectra for the two nonequivalent N atoms in N2O have been measured via Auger electron-photoelectron coincidence spectroscopy. The site-selected Auger spectra are compared with the normal Auger spectrum and with accurate theoretical calculations accounting for the effects of the dynamics of the nuclei on the energy and linewidth of the Auger bands. Such effects are found to be crucial factors in determining the different band shapes in the site-selected spectra.

“…SF 6 , SiF 4 ), and at variance with many smaller molecules (e.g. CO, CO 2 , NO, N 2 O) for which the shape resonance is almost completely suppressed [24,29,30,32], [70]- [72]. Many studies showed that multiple scattering of photoelectrons by neighboring atoms is essential for the interpretation of shape resonance features in x-ray absorption spectra, particularly for large molecules and the solid phase [73]- [76].…”

The state-selective dissociation dynamics for anionic and excited neutral fragments of gaseous SiCl 4 following Cl 2p and Si 2p core-level excitations were characterized by combining measurements of the photoninduced anionic dissociation, x-ray absorption and UV/visible dispersed fluorescence. The transitions of core electrons to high Rydberg states/doubly excited states in the vicinity of both Si 2p and Cl 2p ionization thresholds of gaseous SiCl 4 lead to a remarkably enhanced production of anionic, Si − and Cl − , fragments and excited neutral atomic, Si * , fragments. This enhancement via core-level excitation near the ionization threshold of gaseous SiCl 4 is explained in terms of the contributions from the Auger decay of doubly excited states, shake-modified resonant Auger decay, or/and post-collision interaction. These complementary results provide insight into the state-selective anionic and excited neutral fragmentation of gaseous molecules via core-level excitation.

“…While it had been presumed that negative ion is emitted from singly charged ion states produced by resonant Auger decay of core-excited states, the direct evidence to the mechanism was recently offered by a negative-positive ion coincidence measurement [179]. Lindle and co-workers proved that the observation of negative fragment ions can be a probe to postcollision interaction [180] and to doubly excited states embedded in inner-shell ionization continua [181].…”
