Validity of the adiabatic nuclei theory for vibrational excitation of molecules by electron impact: The e-H/sub 2/ system

Journal Article · · Phys. Rev. A; (United States)
; ;
The widely used adiabatic nuclei approximation of electron-molecule scattering is shown to introduce serious errors into near-threshold e-H/sub 2/ vibrational-excitation cross sections. An alternative method, in which only the rotational motion of the nuclei is treated adiabatically, provides a computationally tractable procedure that yields highly accurate differential and integral cross sections.
