Elastic scattering of electrons by H sub 2 S at 50--1000 eV

A parameter-free spherical optical potential model is used to calculate the elastic differential, integral, and momentum transfer cross sections for the {ital e}{sup {minus}}-H{sub 2}S system in the energy range 50--1000 eV. The optical potential is constructed from a near-Hartree-Fock one-center expansion of a hydrogen sulfide (H{sub 2}S) wave function. The optical potential is then treated in a partial-wave analysis to extract various scattering cross sections.
