Electron screening and electron–electron scattering mechanisms
Journal of Electron Spectroscopy and Related Phenomena, 2013Abstract The roles of binary and multiple scattering are considered in the context of electron scattering and diffraction on the W(1 1 0) and W(1 1 0) + O(1 × 1) surfaces for energies from 10 to 40 eV. We define a binary scattering mechanism as the incident electron interacting with the field of a valence electron with conservation of the total ...

Electron–electron and electron–positron bremsstrahlung
Radiation Physics and Chemistry, 2006Abstract The bremsstrahlung emitted in electron–electron (e–e) and electron–positron (e - –e + ) collisions is investigated. After a short description of the kinematics, cross sections exact to lowest-order perturbation theory are presented and compared with available approximations, and experiments on the two processes are ...

Electron sound in aluminum. Electron–electron scattering
Low Temperature Physics, 1998The relaxation parameters of charge carriers in aluminum are measured by investigating the attenuation of electron sound and acoustic wave transfer under Doppler-shifted cyclotron resonance. It is shown that the electron–electron relaxation rate at spherical parts of the hole sheet of the Fermi surface is close to the results of the theory (A.

Electron–electron interactions in the 2D electron system
Solid State Communications, 2007Abstract In this paper, we report studies of the electron–electron interaction effects in 2D electron systems. The interaction manifests in renormalization of the effective spin susceptibility, effective mass, g ∗ -factor, conductivity etc.

Electronic Markets and Electronic Governments
International Journal of Electronic Commerce, 1997Information technology (IT) has been able to transform the way many business transactions are organized. Mergers, acquisitions, outsourcing, and divestitures are all well-known changes that have resulted from the ability of IT to change the way organizations monitor and coordinate activities.

Electron-Electron and Positron-Electron Scattering Measurements
Physical Review, 1954A counter experiment is described which measures the absolute differential electron-electron scattering cross section in the energy interval 0.6 to 1.2 Mev and the absolute differential positron-electron scattering cross section in the energy interval 0.6 to 1.0 Mev.

Calculation of Electron-Electron Scattering
Physical Review, 1958The matrix elements involved in the calculation of electron-electron and positron-electron scattering are written down explicitiy for a complete set of initial and final spin states of the particles. This permits the evaluation of the cross section for any polarization combination desired, with a minimum of labor. (auth)

Proceedings of the IRE, 1962
Technology can be thought of as a man-made substitute for natural evolution in the process of adjusting to our environment and in which many of the steps of natural evolution are being repeated. The modern human being is the culmination of an eon-long evolutionary process that began with the existence of individual simple cells and culminated in the ...

The study of the electron-electron interaction in electron gun
Microelectronic Engineering, 1986Abstract The paper summarizes the up-to-date study of the electron -electron interaction of beam electrons in columns. The electron-electron interaction of beam electrons results in two effects to influence the electron optical properties of columns: the trejectroy displacement and the the energy spread which is called as Boersch effect.
