Vibrational Excitation of Molecules via Shape Resonances.

Abstract

The paper presents a survey of the progress made in understanding vibrational excitation of molecules by electron impact, with special emphasis on new results obtained in the past year. It is shown that the properties of the shape resonance in the specific molecules determine the behavior of the vibrational cross sections at low energies. Thus the lifetime and the energy of the resonances are determining factors. Examples are given for N2, O2, and CO2. For the case of N2, the cross sections to high vibrational states, up to v = 10 are discussed for the energy range 2-4 eV. For O2, we present data in the energy range 0-14 eV and for CO2, new data for the 3.8 eV resonance are shown. (Modified author abstract)
