Abstract: In this work, we present a joint theoretical and experimental study on electron-H2S collisions in the low- and intermediate-energy range. More specifically, we report measured elastic differential, integral, and momentum-transfer cross sections in the (100-500)-eV energy range. In addition, calculated elastic cross sections in the (0.5-500)-eV energy range are also reported. The measurements were performed using a crossed electron beam-molecular beam geometry. The angular distributions of the scattered electrons were converted to absolute cross sections using the relative flow technique. Theoretically, an optical potential is used to represent the electron-molecule interaction. The Schwinger variational method combined with the distorted-wave approximation is used to solve the scattering equations. The comparison between our calculated and measured results as well as with other available experimental and theoretical data in the literature is encouraging.
