Absolute vibrational cross sections for low energy electron (1-19 eV) scattering from condensed tetrahydrofuran (THF)

Abstract

SynopsisAbsolute cross sections (CSs) for vibrational excitation were obtained for low energy electron impact with tetrahydrofuran (THF) molecules condensed on Ar at 19K. The absolute CSs were measured with a high resolution electron energy loss spectrometer for the 1 to 19 eV incident electron energy range. The values of the vibrational CSs are found to lie within the 10-17cm2 range and to show the effects of resonant excitation.
