The main features observed in the forward spectra are convoy electrons, binary-encounter electrons, and (for the Au target only) a high-velocity tail which we attribute to a Fermi shuttle acceleration mechanism. Backward spectra do not show distinct structures. The spectra allow us to determine...
Cross sections for excitation of the b 3 Σ u + , a Σ g + 3 , and c 3 Π u states of H 2 by low-energy electrons We used a multichannel extension of the Schwinger variational principle [K. Takatsuka and V. McKoy, Phys. Rev. A 24 , 2473 (1981)] to study the cross secti...
Instead of using O2 as an oxidant, we discovered that NicA2 donates electrons to a cytochrome c, which means that NicA2 is actually a dehydrogenase. This is surprising, as enzymes of the flavin-containing amine oxidase family were invariably thought to use O2 as an electron acceptor. Our ...
A study of ionization electrons drifting large distances in liquid and solid argon A two liter gridded ionization chamber was built and operated repeatedly to study electron transport in liquid and solid argon over distances up to 10 cm i... E Aprile,KL Giboni,C Rubbia - 《Nuclear Instruments...
Based solution from 400 on to the Rotating-disk voltammograms of VN/C 2000 rpm in Fig. 4A, the average number of electrode electrons tirnanOsf2e-rsraetudrpateerdo0x.y1g Men KOH mol- ecule involved in VN/C catalyst for ORR is 3.95 which suggests a direct 4-electron reduction ...
The unraveled electronic structure and (photo)electrocatalytic features suggest that a synergistic effect between the electron-rich N3ligands and the Co-N4single-atom sites in the CoPor-N3polymer results in the Co centers attaining more electrons, which is beneficial to facilitating the electron ...
Reflection of electrons by a crystal of nickel Correction for the Schottky Effect has been applied to our measurements upon the thermionic work function of tungsten. For zero field at the filament we obtain the value 4.82 volts for φin the equation i=ATexp. (-φekT) and, as before, .....
Electrons in condensed matter are classified into core electrons and outer electrons (or valence electrons). The core electrons are well localized inside the atom, so that they keep their properties in the free atom state, irrespective o... A Kotani - Springer Berlin Heidelberg 被引量: 318发表...

Computation of the atomic inner-shell excitation cross-sections for fast electrons in crystals Analytical electron microscopes are well suited for producing energy spectroscopic diffraction (ESD) patterns. In particular, an ESD pattern recorded at an... AW&H Kohl - 《Philosophical Magazine Part B》 ...
