(a) Partial ionization cross sections for the Fe 1s, 2s,p, and 3s,p,d shells through absorption of 7200 eV photons26 and through electron-impact.28 (b) Simulated energy and time distributions of incident photons as well as energetic photo- and Auger electrons released in the studied material under irradiation with one X-ray pulse with a flux of 244 × 1030 photon/(s cm2). The data for electrons were integrated over 500 eV energy intervals and 5 fs time periods. The data for photons were integrated over 5 fs time intervals. (c) Illustration of the unique high valence state creation process on the metal site in a Fe(CN)6 molecule under ultrashort intense X-ray pulse irradiation.
