We report a joint theoretical-experimental investigation of electron collision with dimethyl ether (DME) in the low-and intermediate-energy ranges. Experimental absolute differential, integral, and momentum-transfer cross sections for elastic e − -DME scattering are reported in the 100-1000 eV energy range. Our measurements were performed using a crossed electron-beam-molecular-beam geometry. The angular distribution of the scattered electrons was converted to absolute cross section using the relative flow technique. Theoretically, elastic differential, integral, and momentum-transfer cross sections, as well as the grand-total and total absorption cross sections for electron collision with DME are calculated in the 1-1000 eV energy range. A single-center-expansion technique combined with the Padé approximant method is used in our calculations. A comparison between the present experimental and theoretical data shows very good agreement. Moreover, comparison with theoretical and experimental data for e − -ethanol (an isomer of DME) scattering shows interesting isomeric effects.

We present an experimental study on electron scattering by methanol (CH 3 OH). More specifically, differential, integral, and momentum-transfer cross sections for elastic electron scattering in the 100-to 1000-eV energy range are reported. Experimentally, angular distributions of the energy-selected electrons are measured and converted to absolute cross sections using the relative-flow technique. Relative-flow rates measured using the method of pressure decrease are applied for this purpose. The influence of the adsorption-desorption of methanol vapor on the surfaces inside of the gas-handling manifold is also studied. The possibility of dimerization of methanol at low pressures is investigated and disregarded based on the experimental evidence and also on a molecular-dynamics-simulation study. Electron-methanol collision cross sections are also calculated using the independent-atom model at the static-exchange-polarization and static-exchange-polarization-absorption levels of approximation. The comparison of our measured results of cross sections with other experimental and theoretical data available in the literature and with the present calculated data is encouraging.

A joint experimental-theoretical study on electron-SO 2 collisions in the low and intermediate energy range is reported. More specifically, experimental elastic differential, integral, and momentum transfer cross sections in absolute scale are measured in the 100-1000 eV energy range using the relative-flow technique. Calculated elastic differential, integral, and momentum transfer cross sections as well as grand-total and total absorption cross sections are also presented in the 1-1000 eV energy range. A complex optical potential is used to represent the electron-molecule interaction dynamics, whereas the Schwinger variational iterative method combined with the distorted-wave approximation is used to solve the scattering equations. Comparison of the present results is made with the theoretical and experimental results available in the literature.
