Cross sections for the electron-impact excitation of the n=2 states of the heliumlike ions Fe xxv and Kr xxxv are calculated in the relativistic distorted-wave approximation. Both bound-core orbitals and continuum-scattering orbitals are calculated using the Dirac Hamiltonian. The most significant ...
50 nA (400 nA configuration also available) Standard sample holder Multi-purpose holder, uniquely mounts directly onto the stage, hosts up to 18 standard stubs (Ø12 mm), three pre-tilted stubs, cross-section samples and two pre-tilted row-bar holders (38° and 90°) and does ...
The Fe 3d-derived states are revealed by the valence-band XPS spectra and the Fe 3p core resonance photoemission spectra. The spectra are analyzed by configuration-interaction calculation on the FeS4 cluster model; the analysis yields the S 3p→Fe 3d charge-transfer energy Δ close to zero...

The 1A1g ground state has one allowed excited configuration, t2g6eg1, resulting in a 2E doublet excited absorption state that gives rise to observed single pre-edge feature (Fig. 5)47. Fig. 5: XAS of the [FeCo] crystals. a Temperature-dependent Fe K-edge X-ray absorption spectroscopy ...
59 Today’s aberration-corrected electron microscopes can provide lattice-resolution or even atomic-resolution images at these ‘low’ primary energies that can reveal the precise atomic configuration of point defects or grain boundaries. It should be noted that, although the graphene lattice is ...
The B-ring hydroxyl configuration is the most significant determinant of ROS and RNS scavenging, whereas substitution of the rings A and C has little impact on O2– radical scavenging rate constants [9]. Hydrogens and electrons are donated by ring B hydroxyl groups to hydroxyl, peroxyl, and ...
