Excitation of the lowest electronic transitions in ethanol by low-energy electrons

We report absolute differential and integral cross sections for electronic excitation of ethanol, by low-energy electron impact. Cross sections for low-lying excited states were measured at incident electron energies from 9 to 20 eV and at scattering angles from 5° through 130°. Our results include cross sections for excitation of the 1^3A" and 1^1A" states as well as for the 2^3A"+ 1^3A' and 2^1A" + 2^1A'+ section sums. Corresponding calculations were also performed using the Schwinger multichannel method, within an 11-channel close-coupling scheme.
