| Popis: | International audience; We apply a spectrally-resolved electron interferometry technique to the measurement of the spectral phase in the vicinity of the 3s13p64p Fano resonance of argon. We show that it allows disentangling the phases of the two nearly-overlapping electron wavepackets corresponding to different spin–orbit final states. Using simple assumptions, it is possible to process the experimental data and numerically isolate each component in a self-consistent manner. This in turn allows reconstructing the autoionization dynamics of the dominant channel. |
