Abstrakt:
Reliable cross-sections for electron-molecule collisions are urgently needed for numerical modeling
of various processes important from technological point of view. Unfortunately, a significant progress in
theory and experiment over the last decade is not usually accompanied by the convergence of cross-sections
measured at different laboratories and calculated with different methods. Moreover the most advanced contemporary
theories involve such large basis sets and complicated equations that they are not easily applied
to each specific molecule for which data are needed. For these reasons the search for semi-empirical indications
in angular and energy dependencies of scattering cross-section becomes important. In this paper we
make a brief review of the applicability of the Born-dipole approximation for elastic, rotational, vibrational
and ionization processes that can occur during electron-molecule collisions. We take into account the most
recent experimental findings as the reference points.
