Abstract

We present an extension of the method of discrete momentum representation to the calculation of elastic electron scattering from polar molecules. The essence of this method is the subtraction of the first Born term from the Lippmann-Schwinger equation, which is solved for a modified interaction potential from which the long-range part is removed. Forward scattering is described in the first Born approximation. The use of this method is demonstrated for electron scattering from the H2O molecule in the static-exchange approximation. The results are in good agreement with former calculations as well as with experiments.
