摘要：

We report absolute differential cross section measurements for vibrationally elastic electron scattering from NH3 at incident energies from 2-30 eV. The present results, from a crossed electron-molecular beam apparatus, represent the first comprehensive experimental attempt to quantify the elastic electron-NH3 scattering process. At each energy studied we have integrated our differential cross section dat to generate total elastic and elastic momentum transfer cross sections and a critical comparison of both our differential and integral cross sections against previous experiment and theory is provided. We also report our observation of a strong Feshbach resonance in the elastic channel at an energy of 5.59 +/- 0.05 eV.
