New Survey of Electron Impact Cross Sections for Photoelectron and Auroral Electron Energy Loss Calculations

摘要: Newly surveyed sets of energy loss cross sections are presented for N2, O2, and O. The work was motivated by a number new electron measurements in the late 1980s early 1990s recent selected review articles. Each set includes total ionization section excitation that correspond to all important non-ionizing channels species. A each species is constructed summing elastic scattering with sections. sum compared measured obtained from transmission experiments. Good agreement achieved three function also Bethe formula above 100 eV. which dominated ion secondary production. Fluxes photoelectrons auroral electrons have been calculated loss...
