Measurement of attosecond photo-ionization delay in xenon

This work presents an experimental data obtained using a method from an atomic system, xenon, from which more different electron wavepackets including shake-up electron wavepackets are emitted, and where a spectral overlap of some of these wavepackets can be observed. The spectral overlap of the different emitted electronic wavepackets can eliminate the relative phase ambiguity, and thus allows for a more reliable measurement of the relative emission phase and delay. In the experimental data , the streaking of the 5p, 5s and 4d photoelectrons and the 5p-25d shake-up satellite from xenon is well resolved, and the Auger lines and corresponding sidebands are individually resolved.
