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.},
