摘      要：Radiative and Auger cascade following the 2p shell vacancy creation in the Fe2+ ion is studied by analysing transitions among energy levels and subconfigurations. Branching ratios of the cascade are analysed and main decay mechanisms are identified for all levels of the Fe3+ 2p(5)3d(6) configuration. The study shows that ion yield strongly depends on the level the cascade starts from. The cascade produces the Fe4+ and Fe5+ ions with the highest population. The ion yields are presented for all levels of the Fe3+ 2p(5)3d(6) configuration. The time-dependent study for population of the ions demonstrates that it takes approximately 10(-16) s for the Fe4+ ions to appear. The final states of the cascade are reached in similar to 10(-3) s. Radiative and Auger spectra produced by cascade span the energy region up to similar to 780 eV. (C) 2020 Elsevier Inc. All rights reserved.
