Abstract
Normalized experimental differential and integral cross sections for vibrationally elastic scattering of low-energy electrons from isobutanol are presented. The differential cross sections are measured at incident energies from 1 to 100 eV and scattering angles from to . These cross sections are compared to earlier experimental and theoretical results for isobutanol and -butanol, as well as to results for smaller alcohols and for alkanes. Further comparisons are made with calculated cross sections for isobutylamine and for smaller amines, including ethylamine dimethylamine , the two isomers -propylamine and isopropylamine, and ethylene diamine The calculated cross sections are obtained using the Schwinger multichannel method. The comparisons illuminate the role of molecular structure in determining the angular distribution of resonantly scattered electrons.
