Low energy electron-impact ionization of CF4.

POSTER

Abstract

Experimental and theoretical triple differential cross section results will be presented for 66 eV electron-impact ionization of CF4 for the three unresolved outermost orbitals - the highest, next highest, and next-next highest occupied molecular orbitals (HOMO, NHOMO, and HOMO-2). The theoretical results will be compared with experiment for in plane scattering and full perpendicular plane scattering with projectile scattering angles of 8$^{\mathrm{o}}$, 10$^{\mathrm{o}}$, 12$^{\mathrm{o}}$, 15$^{\mathrm{o}}$, and 20$^{\mathrm{o}}$ at ejected electron energies of 3, 5, 8, and 10 eV. Comparisons will be made with theoretical M3DW (molecular 3-body distorted wave) model calculations.
