Elastic scattering of electrons from SO/sub 2/
Using a crossed electron beam--molecular beam scattering geometry and the relative-flow technique, ratios of elastic differential cross sections of SO/sub 2/ to those of He have been measured at electron impact energies of 12, 20, 50, 100, 150, and 200 eV. At each energy, an angular range of 15/sup 0/ to 150/sup 0/ has been covered. These ratios have been multiplied by previously known He elastic differential cross sections to obtain elastic differential cross sections for SO/sub 2/. From a knowledge of differential cross sections, integral and momentum transfer cross sections have been determined. Using the two-potential theory of e-molecule scattering, calculations were also performed and compared with the measurements.
