Abstract

Total electron scattering cross sections for pyrazine in the energy range 10–500 eV have been measured
with a new magnetically confined electron transmission-beam apparatus. Theoretical differential
and integral elastic, as well as integral inelastic, cross sections have been calculated by means of a
screening-corrected form of the independent-atom representation (IAM-SCAR) from 10 to 1000 eV incident electron energies. The present experimental and theoretical total cross sections show a good level of agreement, to within 10%, in the overlapping energy range. Consistency of these results with previous calculations (i.e., the R-matrix and Schwinger Multichannel methods) and elastic scattering measurements at lower energies, below 10 eV, is also discussed.
