Surface Plasmons Excited by X-rays in the Surface Layers of Solids

open access: yesSolids, 2022
The phenomenon of total external reflection of X-rays at a sliding angle of incidence of a beam of incident X-rays is investigated. For metals, a quantitative law of direct dependence of the refractive index decrement on the interplane distance is ...

Development of the Colle-Salvetti correlation-energy formula into a functional of the electron density.

open access: yesPhysical Review B (Condensed Matter), 1988
A correlation-energy formula due to Colle and Salvetti [Theor. Chim. Acta 37, 329 (1975)], in which the correlation energy density is expressed in terms of the electron density and a Laplacian of the second-order Hartree-Fock density matrix, is restated ...

Collision of a Positron with the Capture of an Electron from Lithium and the Effect of a Magnetic Field on the Particles Balance

open access: yesChemosensors, 2021
The processes of scattering slow positrons with the possible formation of positronium play an important role in the diagnosis of both composite materials, including semiconductor materials, and for the analysis of images obtained by positron tomography ...

Comparison of Megavoltage Electron Dosimetry Beams in Radiation Therapy Using Different Protocols [PDF]

open access: yesJournal of Kerman University of Medical Sciences
Background: International Atomic Energy Agency (IAEA) and American Association of physicist in Medicine (AAPM) have introduced new protocols for dosimetry of electron and photon megavoltage beams and increased them to more than five protocols at the ...

Evaluation of the protective effect of inactivated foot and mouth disease subtype A-IRAN-05 using an electron beam in a guinea pig model [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2023
Foot and Mouth Disease Virus (FMDV) can cause a lot of economic losses in livestock. In this research FMDV subtype A-IRAN-05 was used. FMDV was multiplied on BHK21 cells and irradiated by electron beam (10, 20, 25, 30, 35, 40, 45, 50 kGy), then the dose ...

Impact of Electron-Electron Cusp on Configuration Interaction Energies [PDF]

open access: yesJ. Chem. Phys. 115, 1626 (2001), 2001
The effect of the electron-electron cusp on the convergence of configuration interaction (CI) wave functions is examined. By analogy with the pseudopotential approach for electron-ion interactions, an effective electron-electron interaction is developed which closely reproduces the scattering of the Coulomb interaction but is smooth and finite at zero ...

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY

open access: yesJournal of Cell Biology, 1963
Aqueous solutions of lead salts (1, 2) and saturated solutions of lead hydroxide (1) have been used as stains to enhance the electron-scattering properties of components of biological materials examined in the electron microscope.

Electron thermal conductivity owing to collisions between degenerate electrons [PDF]

open access: yesPhys.Rev. D74 (2006) 043004, 2006
We calculate the thermal conductivity of electrons produced by electron-electron Coulomb scattering in a strongly degenerate electron gas taking into account the Landau damping of transverse plasmons. The Landau damping strongly reduces this conductivity in the domain of ultrarelativistic electrons at temperatures below the electron plasma temperature.

Bilepton Resonance in Electron-Electron Scattering [PDF]

open access: yes, 2000
Theoretical backgound for bileptonic gauge bosons is reviewed, both the SU(15) GUT model and the 3-3-1 model. Mass limits on bileptons are discussed coming from $e^+e^-$ scattering, polarized muon decay and muonium-antimuonium conversion. Discovery in $e^
