Title: Angle-resolved electron-energy-loss study of core-level electron excitation in molecules: Determination of the generalized oscillator strength for the carbon 1 s (2. sigma. sub g r arrow 2. pi. sub u ) excitation in CO sub 2

Abstract

As part of a systematic, quantitative study of the angle dependence of core-level-electron excitation by electron impact, we have determined the generalized oscillator strength (GOS) for the carbon 1{ital s}(2{sigma}{sub {ital g}}{r arrow}2{pi}{sub {ital u}}) transition in CO{sub 2}. The experimental results were obtained at an impact energy of 1290 eV, in the angular range of 2{degree}--14{degree}, with an energy resolution of 0.9 eV. Theoretical values for the GOS were also obtained, using {ital ab} {ital initio} Hartree-Fock molecular wave functions and allowing for the relaxation of all the molecular orbitals in the determination of the excited-state wave function.
