The indirect double photoionization of Kr via the Kr+(3d3/2,5/2-1) states to the Kr2+(4s4p5 1Po) final state has been studied by Auger electron-photoelectron angular resolved coincidence experiments. By tuning the incident photon energy, we succeeded in observing the coherence in the photoionization of two nondegenerate spin-orbit states. The observations have been described quantitatively by a model which accounts for the two pathways to the final state as well as for the indistinguishability of the two ejected electrons.

Abstract
The indirect double photoionization of Kr via the Kr+(3d3/2,5/2-1) states to the Kr2+(4s4p5 1Po) final state has been studied by Auger electron-photoelectron angular resolved coincidence experiments. By tuning the incident photon energy, we succeeded in observing the coherence in the photoionization of two nondegenerate spin-orbit states. The observations have been described quantitatively by a model which accounts for the two pathways to the final state as well as for the indistinguishability of the two ejected electrons.File in questo prodotto:
