Abstract
The pronounced oscillations in the e-N2 cross section at 2 eV provide a convenient energy standard in low-energy electron scattering experiments. The positions of the first five peaks have been recalibrated with an accuracy of 12 meV. The sharp step structure in the v=1 excitation function at the v=2 threshold in e-HF scattering has been employed as a calibration mark. Results are given for 20 degrees , 60 degrees and 120 degrees scattering angles.
