Electron momentum-transfer cross sections of tungsten, silicon, and silicon dioxide at energies from 0.1 to 10,000 eV.

摘要

For the purpose of estimating effective stopping of low energy electrons in a particular direction, the momentum-transfer cross sections of Tungsten, Silicon, and Silicon Dioxide are furnished. The elastic scattering momentum-transfer cross sections are obtained by integration over the differential elastic scattering cross sections either in the individual references or in this paper numerically. At 10eV and below the elastic scattering momentum-transfer cross sections were also obtained (Itikawa) from the total scattering cross section, swarm experiments and the microwave method, as well as theoretical calculations. The inelastic collision momentum-transfer cross sections were calculated from the electron stopping powers by an approximate theory due to Devaney. The total momentum-transfer cross section is then the sum of the elastic scattering and the inelastic collision cross sections. 9 refs., 4 tabs.
