Theoretical doubly differential and integral cross sections for elastic scattering of electrons by hydrogen sulfide vapor are here reported for impact energies ranging from 10 eV to 10 keV. The calculations are carried out within the partial-wave formalism by means of a spherical complex optical potential model taking into account a static contribution deduced from a single-center Hartree–Fock target description as well as correlation–polarization and exchange effects. The results clearly point out the role played by the exchange and the correlation–polarization in particular at low incident energies and around the observed minima. Both doubly differential and integral cross sections are finally compared with a large set of experimental data and a satisfactory agreement is observed.
