Abstract : The expansion method i used to study the elastic scattering of slow electrons by heavy atoms. Calculations are made of the S, P, D and F- cross-sections of elastic scattering by Hg and Ca without taking exchange into account, and of the S-cross-section on Hg taking exchange into account. To control the accuracy of calculations by the expansion method calculations are carried out by Drukarev's method of integral equations for the S-cross-section of elastic scattering by Hg without taking exchange into account. For the cross section of elastic scattering of electrons by Hg, a comparison with experimental data is made. The accuracy of the wave functions of a scattered particle obtained by the expansion method is examined. (Author)
