Abstract: Postcollision interaction (PCI) in near-threshold photoionization of the 𝐾 shell of atomic Xe is investigated with hard-x-ray synchrotron radiation. Applying Auger electron spectroscopy, line-shape distortion is monitored in the $𝐾−𝐿_2→𝐿_2𝑀_{4,5}𝑀_{4,5}$ decay channel, where the initial $𝐾−𝐿_2$ $(𝐾𝛼_2)$ x-ray-emission step mediates the emission of the two continuum electrons. The 𝐾-edge result is compared to similar data obtained on direct $𝐿_2𝑀_{4,5}𝑀_{4,5}$ decay at the $𝐿_2$ edge without x-ray-emission. It is found that the evolution of the PCI shift with excess photon energy is very similar at both edges, but a subtle decrease in the PCI shift is observable at the 𝐾 edge due to the effect of the ultrafast x-ray emission step delaying the PCI energy exchange by a few attoseconds.
