Using a spectrally resolved electron interferometry technique, we measure photoionization time delays between the 3s and 3p subshells of argon over a large 34-eV energy range covering the Cooper minima in both subshells. The observed strong variation

We study helium two-photon ionization using attosecond electron interferometry in a velocity-map imaging spectrometer. The complete dynamics of the photoemission process is then reconstructed in space and time.

International audience; Laser-dressed photoemission spectroscopy has established itself as the gold standard of attosecond temporal metrology. In this technique, the attosecond structure of an extreme-ultraviolet pulse is retrieved from the wave func
