Interference effects in the Ne double photoionization studied by photoelectron-Auger-electron coincidence experiments - art. no. 044702

The resonant double photoionization of Ne has been studied via an electron- electron coincidence experiment at a photon energy of 92.71 eV. At this ene rgy, the kinetic energy of the photoelectrons matches exactly the energy of the Auger electrons. The overall experimental energy resolution, narrower than the natural linewidth of the intermediate state, has allowed us to obs erve angular- and energy-dependent interference effects due to the indistin guishability of the two electrons.
