摘要：

The influence of a long-range potential (other than the dipole one) on electron scattering by polar molecules is investigated. For this purpose the effective range theory for electron scattering by the potential with a long-range part -(D cos theta /r2)+( alpha /2rs) is developed. To simplify the investigation the angular dependence of the alpha /2rs potential is ignored. Formulae for the low-energy behavior of K matrix elements are obtained. These formulae are used to estimate the influence of the quadrupole interaction on the total and momentum transfer cross sections for electron scattering from CsF molecules.
