Integral Electron Scattering Cross Sections from N₂O for Impact Energies Ranging from 1 to 1000 eV

Accurate total cross sections (TCS), within 5%, for electron scattering by N₂O molecules have been measured with a magnetically confined electron transmission apparatus for impact energies ranging from 1 to 200 eV. For higher energies, these measurements have been complemented with our independent atom-based screening corrected additivity rule, including interference (IAM-SCAR + I) method to determine a complete reference TCS data set in the energy range (1-1000 eV). After a critical discussion that includes our calculated integral elastic and ionization cross sections and the theoretical and experimental data available in the literature, a complete set of integral elastic and inelastic (rotational, vibrational, and electronic excitation, ionization and electron attachment) cross sections, consistent with the reference TCS data, have been derived. This update on the N₂O collisional database may help to improve the accuracy of radiation-induced transport models.
