3p-excitation of atomic Mn; experimental evidence for the super Coster-Kronig decay

Attosecond pump–attosecond probe spectroscopy of Auger decay

“…4 In such cases, time-resolved spectroscopy powered by the availability of attosecond pulses turns out to be a viable alternative to study Auger dynamics. Time-resolved spectroscopy of Auger dynamics is also needed to shed light on some electronic processes that remain poorly understood, for instance the ultra-fast super-Coster-Kronig decays, 5 where photoionisation and the Auger decay can occur on the similar time scale, leading one to question the basic two-step picture of the process, or Coster-Kronig decays in the inner valence shell in molecules, where multiple overlapping resonances can lead to rich decay patterns that differ from a simple exponential decay.…”

“…Arguing about decay probabilities and matrix elements, Dietz et al [10] was the first to explain Fano resonance occurring at the 3p threshold absorption. The interference was said to be occurring between the direct (3p 6 3d 9 + hν → 3p 6 3d 8 f ) and indirect (3p 6 3d 9 + hν → 3p 5 3d 10 → 3p 6 3d 8 f ) processes involving super-Coster-Kronig (SCK) [11,12] transitions, which gave rise to the characteristic Fano line shape.…”

Multiple Auger cycle photoionisation of manganese atoms by short soft x-ray pulses

“…resonance was studied in the past using absorption spectroscopy for neutral manganese [41,42] as well as for Mn 1+ to Mn 3+ [41,[43][44][45][46][47][48][49]. In case of the singly charged Mn 1+ ion the absolute value of the cross section has been determined [50].…”
