    Abstract

    Experimental results are reported for elastic differential and integral cross sections for electrons scattering from iodomethane (CH3I). These measurements were made at seven incident electron energies in the range 5-50 eV, with a scattered electron angular range of 20°-135°. Corresponding calculations using the independent atom method plus screened additivity rule (IAM-SCAR), both with and without a dipole correction, are also reported as a part of this study. Where possible, comparison is made to the only other set of experimental results available in the literature (Kato et al 2010 J. Chem. Phys. 132 074309) and to calculated cross sections from the Schwinger multichannel approach at the static exchange level (Natalense et al 2001 Braz. J. Phys. 31 15). In general, good agreement is found between the present measurements and IAM-SCAR computations, and between our results and the earlier investigations.
