Experimental and theoretical electron-scattering cross-section data for dichloromethane

8 pags., 4 figs., 4 tabs.We report on a combination of experimental and theoretical investigations into the elastic differential cross sections (DCSs) and integral cross sections for electron interactions with dichloromethane, CH2Cl2, in the incident electron energy over the 7.0-30 eV range. Elastic electron-scattering cross-section calculations have been performed within the framework of the Schwinger multichannel method implemented with pseudopotentials (SMCPP), and the independent-atom model with screening-corrected additivity rule including interference-effects correction (IAM-SCAR+I). The present elastic DCSs have been found to agree reasonably well with the results of IAM-SCAR+I calculations above 20 eV and also with the SMC calculations below 30 eV. Although some discrepancies were found for 7 eV, the agreement between the two theoretical methodologies is remarkable as the electron-impact energy increases. Calculated elastic DCSs are also reported up to 10000 eV for scattering angles from 0° to 180° together with total cross section within the IAM-SCAR+I framework.K.K. and F.F.S. acknowledge the Portuguese National Funding Agency FCT through Grant No. SFRH/BD/52536/2014 and Researcher Contract No. IF-FCT IF/00380/2014, and, together with P.L.V., the Research Grant No. UID/FIS/00068/2013.
