The scattering of low energy electrons from hydrogen sulphide

Abstract

Absolute differential cross sections for vibrationally elastic electron scattering from hydrogen sulphide (H2S) have been measured using a crossed electronic-molecular beam apparatus at incident energies from 1-30 eV and scattering angles between -20 and 130°. At each energy studied we have integrated our differential cross section data to obtain total elastic and elastic momentum transfer cross sections. Vibrational excitation of H2S by electron impact has also been studied at incident energies of 2 and 3 eV, in the region of the law energy shape resonance. Both our differential and integral cross sections are compared with previous experimental studies and calculated values. Show more
