Electron-impact single ionization is investigated for the levels of the ground 3d5 and long-lived 3d44s configurations of the Fe3+ ion. In addition, the Maxwellian rate coefficients are tabulated in the study. The difference among the cross sections reaches 11% and 17% for the levels of ...
The most significant relativistic effects result from the spinorbit mixing of the 2 Pand 2 Pexcited states. We compare our results with previous calculations based on a perturbation-theory treatment of relativistic effects.关键词: atomic and molecular physics electron-ion collisions excitation iron ...
We have measured electron-ion recombination for Feforming Feand for Feforming Feusing a merged beams arrangement at the TSR heavy-ion storage ring in Heidelberg, Germany. The measured merged beams recombination rate coefficients (MBRRC) for relative energies from 0 to 75 eV are presented, ...
We have measured electron-ion recombination for Fe XII forming Fe XI using a merged-beam configuration at the heavy-ion storage ring TSR located at the Max Planck Institute for Nuclear Physics in Heidelberg, Germany. The measured merged-beam recombination rate coefficient (MBRRC) for collision ...
Energetic analysis devoted to the Fe2+ electronic spin configuration and to the ion position in the surfaces reveals that Fe2+ in its quintet state and placed at the outermost positions of the slab constitutes the most stable Fe-containing surface, which is related to the higher stability of ...
On the basis of these spectroscopic and theoretical analyses, 1 is best described as containing an intermediate spin Fe(II) ion, whereas for the corresponding cobalt complex, oxidation states describing a d6 (CoIII) or d7 (CoII) electron configuration cannot be unambiguously assigned. The ...
Electron transparent TEM lamellae of the samples were fabricated using focused ion beam/scanning electron microscope (FIB/SEM) by FEI Helios NanoLab 660. The lamellae were imaged using a FEI Titan Themis 60-300 Cubed high resolution (scanning) transmission electron microscope (HR-TEM) at 300 kV...
electron energy loss spectroscopy (EELS) analysis (Fig.1eand Supplementary Fig.6). The EELS profile of the nanoparticle shows strong Fe and O signals, and the Pt signal could not be detected owing to the high energy loss (around 2,200 eV) of the Pt major peak18. The profile of the...
O2@6, O2@6a, and O2@6I is weaker than that in O2@FeN4(Fig.2f). Therefore, the origin of O2activation is the hybridization of the Fe 3dz2(3dyz) and *O22pz (2py) orbitals, which results in electron transfer from the Fe site to *O2, breaking the Fe 3dz2(3dyz) and O22pz (...
