Total electron scattering cross section from pyridine molecules in the energy range 10–1000 eV

Highlights: • Total electron scattering cross section measurements from pyridine (10–1000 eV). • Update of our IAM-SCAR method by including interference effects. • Experimental and theoretical data in reasonable agreement, within uncertainty limits. • Interference effects for differential and integral cross sections are discussed. • Valuable data set for modelling radiation damage procedures. We report on experimental total electron scattering cross-section (TCS) from pyridine (C₅H₅N) for incident electron energies between 10 and 1000 eV, with experimental uncertainties within 5–10%, as measured with a double electrostatic analyser apparatus. The experimental results are compared with our theoretical calculations performed within the independent atom model complemented with a screening corrected additivity rule (IAM-SCAR) procedure which has been updated by including interference effects. A good level of agreement is found between both data sources within the experimental uncertainties. The present TCS results for electron impact energy under study contribute, together with other scattering data available in the literature, to achieve a consistent set of cross section data for modelling purposes.
