For many elements K β /K α ratio measurements have been performed using excitation by protons, electrons and ions (Berenyi et al 1978). Only for heavy-ion excitation's the ratio generally dependent upon the exciting ion and upon the energy of the ion (Richard et al 1970). An ...
Abstract —By the methods of atomic force microscopy (AFM) we investigate the surfaces of samples of K-208 glass after separate and combined irradiation in a vacuum chamber with a residual pressure of p v = 104 Pa with protons and electrons with energies of 20 and 30 keV, respectively. At...
Tables for Born Approximation Calculations of K- and L- Shell Ionization by Protons and Other Charged Particles Tables are presented for the calculation of the Born cross sections for ionization by proton impact of K - and L -shells and of individual L -subshells in ... GS Khandelwal,BH Ch...
Five slow Kmesons have been found in the same emulsion volume; in 3 cases the secondary could not be identified, one case is probably a Kdecay and one other a Kdecay. One possible case of a Kmeson is also discussed.关键词: physics angular distribution decay electrons emission energy range...
For example, it can be used to calculate the force between two electrons in an atom, or the force between two protons in the nucleus of an atom. It is also used in engineering fields, such as designing electrical circuits and analyzing the behavior of charged particles in electromagnetic ...
K-shell Core Electron Excitations in the Electronic Stopping of Protons in Water to the electronic stopping power, the K-shell electrons play a rather minor role in terms of the excitation density: Only one percent of the hole population comprises K-shell holes, even at the high proton velocit...
The electrical resistivity of liquid metallic hydrogen at a temperature of 3000 K and a density of 0.35 mol/cm 3 is calculated. Hydrogen is considered as a three-component system consisting of electrons, protons, and neutral hydrogen atoms. The second order of perturbation theory in electron-prot...
This is accomplished by moving the electrons through the membrane using redox reactions that involve both protons and electrons in the overall reaction. The major goal of research in my group is to develop a complete understanding of the different mechanistic paths through which electron and proton ...
X-ray Production by 1.5–11 MeV Protons K -shell ionization and L x-ray production cross-sections by proton impact have been determined from measurements of K x-ray yields from thin targets of ... R Akselsson,TB Johansson - 《Zeitschrift für Physik A Hadrons and Nuclei》 被引量: 83发...
·O2−radicals. Compared to oxygen production via four-electron process, these species are formed easily via two-electron process, beneficial to produce a large-scale source of electrons and protons for water reduction. Therefore, the Co-P/BP nanosheets exhibit robust hydrogen-evolving activity ...
