[1] We investigate the spatial structure of the electron diffuse aurora during the 19 October 1998 storm by comparing drift-loss simulations with precipitating particle data and auroral images. Distributions of precipitating diffuse aurora during magnetic storms depend on variation of the magnetotail electron distributions, electron transport, and electron pitch-angle scattering. In our simulat...

The general theory of matter field interaction is developed for use with scattering phenomena and applied to Compton scattering, of a photon from an initially stationary electron. The method is based on the ECE wave equation, which defines the R parameter of scattering theory. The wave equation is augmented by the minimal prescription and the relativistic Hamilton Jacobi equation. An expression...

One of the most important physical parameters to describe the quality of a piece of semiconductor material is the electron scattering length le. Also referred to as the mean-free path, it stands for the average distance between the randomly distributed scatterers in the material, such as lattice defects, impurities, and phonons. The electron mean-free path is typically a few nanometers (1 nm = ...

The longitudinal asymmetry due to Z0 exchange is calculated in quasi-elastic electron-deuteron scattering at momentum transfers |Q2| ' 0.1 GeV2 relevant for the SAMPLE experiment. The deuteron and pn scattering-state wave functions are obtained from solutions of a Schrödinger equation with the Argonne v18 potential. Electromagnetic and weak neutral oneand two-nucleon currents are included in th...

Recent measurements [R. Panajotovic, M. Jelisavcic, R. Kajita, T. Tanaka, M. Kitajima, H. Cho, H. Tanaka, and S. J. Buckman, J. Chem. Phys. 121, 4559 (2004)] and calculations [C. Trevisan, A. E. Orel, and T. N. Rescigno, Phys. Rev. A 70, 012704 (2004)] of the elastic electron cross section for C(2)F(4) differ materially from our earlier calculations [C. Winstead and V. McKoy, J. Chem. Phys. 116...

This article presents a review of the field of inclusive quasi-elastic electron-nucleus scattering. It discusses the approach used to measure the data and includes a compilation of data available in numerical form. The theoretical approaches used to interpret the data are presented. A number of results obtained from the comparison between experiment and calculation are then reviewed. The analog...

Several dynamic thermal and nonthermal scattering processes affect ultrafast heat transfer 7 in metals after short-pulsed laser heating. Even with decades of measurements of electron8 phonon relaxation, the role of thermal vs. nonthermal electron and phonon scattering on 9 overall electron energy transfer to the phonons remains unclear. In this work, we derive 10 an analytical expression for th...

We calculate electron-hole generation and recombination rates for Coulomb scattering (Auger recombination and impact ionization) in Graphene. The conduction and valence band dispersion relation in Graphene together with energy and momentum conservation requirements restrict the phase space for Coulomb scattering so that electron-hole recombination times can be much longer than 1 ps for electron...

This paper presents the calculation of electron mobility of GaN at various temperatures using Relaxation Time Approximation (RTA) method. The effect of dislocation scattering on electron mobility in GaN is studied. We have discussed about the role of important scattering mechanisms in GaN. The electron mobility values thus obtained are compared with other available experimental and theoretical ...

The first order polarization dependent electron multiple scattering theory of Toptygin has been evaluated for realistic experimental conditions. The result is a prediction of essentially no beam depolarization. Recent experiments are discussed, and calculations are made to illustrate the influence of multiple scattering on Mott double scattering asymmetries. (Submitted to Phys. Rev.) * Supporte...
