Beschreibung:
  • The cascaded Auger decay following ionization or excitation with 94 eV soft-X-ray pulses from the 3d subshell in krypton has been energy-and-time-resolved for the first time. The decay time of the 4s (-1)4p (-2) nl -> 4p (-3) + e and/or 4s (-1)4p (-1) nl -> 4p (-2) + e transition is measured to be 74 +/- 20 fs. Furthermore, our data shows that the electrons with a kinetic energy around 25 eV (generally assigned as 3d (-1) np -> 4s (-2) n'p + e) emitted after core excitation are emitted in a second decay step suggesting an alternative assignment of the form 4s (-2) np 4p (-2) + e.
