Some recent experiments on inelastic electron‐molecule collisions at low energies

This work describes a novel trochoidal electron spectrometer and illustrates its properties on a few examples. In the first example vibrational excitation in the small molecules H 2 and N 2 is measured. Comparison of the results with theoretical work points to the neccessity of using non local methods for correct treatment of near‐threshold region and of extremely short‐lived resonances. In the second example the observation of resonant autodetachment of Feshbach resonances in many organic molecules is reported.
