Manifestation of Auger Resonant Raman Effect on Double-Spectator Type Auger Transitions in the Ne [1s2p](3P)3p2 1P Resonant Double Excitation Region

We have measured the relative intensities of double-spectator type resonant Auger (RA) transitions leading to the Ne + [2 p 3 ]3 p 2 final ionic states from the [1 s 2 p ]( 3 P)3 p 2 1 P doubly excited state of Ne, where square brackets indicate hole states, as a function of excitation photon energy. The intensity curve measured across the double excitation resonance, which locates at 902.45 eV, was analyzed based on the theory of radiationless resonant Raman scattering. We present, for the first time, the results which have manifested the characteristic behaviour of the Auger resonant Raman effect on the double-spectator type RA transition associated with the [1 s 2 p ]3 p 2 multiply-excited intermediate state. The resonance energy and natural width of the doubly excited state determined by the Fano profile fitting to the absorption spectrum have been validated through the measurement with constant-ionic-state scan for these double-spectator type RA decay channels.
