[en] The validity of the Glauber calculations [Ashihara et al.: J. Phys. Soc. Japan 38 (1975) 1732], which have successfully explained the angular distribution for the title process, is investigated by assuming a pure dipole interaction and using an accurate procedure within the framework of the adiabatic approximation. Numerical calculations have been carried out for 4.77 eV electrons scattered by CsCl. It is confirmed that the Glauber approximation gives correct angular distributions in the small-angle region below 50 degrees. The question for the unsuitableness Born approximation in this subject is answered by using the partial wave analysis of the Born differential cross section and the perturbation expansion of the accurate expression in the adiabatic approximation.
