Abstract

We have measured the relative intensity of the photoemission channel leading to the ${Ne}^{+} [2 p^{2}] ({}^{1}D) 3 p {}^{2}P$ final ionic state as a function of excitation photon energy, where square brackets indicate hole states, across the $[1 s 2 p] ({}^{3}P) 3 p^{2} {}^{1}P$ double-excitation resonance. Resonant enhancement is observed in the intensity’s variation curve, we find that the enhancement is definitely seen at the double-excitation resonance, i.e., 902.4 eV. The result confirms the spectator-participator–type resonant Auger transition associates with the $[1 s 2 p] ({}^{3}P) 3 p^{2}$ doubly excited state.
