Abstract: We present a combined theoretical and experimental absolute differential (DCS) and integral (ICS) cross sections for elastic electron scattering from halothane molecule in the intermediate energy range from 50 to 300 eV, which is motivated by its evident impact on global warming and ozone depletion. Experiments were carried out in the angular range from 20 to 110 degrees using a crossed-beam-based equipment. Using argon as the reference gas, relative DCSs were normalized on an absolute scale using the relative flow technique. These DCSs were then extrapolated and integrated to generate experimental ICS. With the use of an independent atom model and the screening corrected additivity rule with interference effects incorporated (IAM-SCAR+I), the theoretical differential and integral cross sections were calculated. In the whole energy and angular range, calculated cross sections agree well with experimental measurements.
