Description

A synchrotron photoionisation technique has been used in an electron spectrometer at the SERC-Daresbury Laboratory, to study electron-molecule scattering. We have shown that it is possible to achieve electron scattering at photon resolution down to an energy resolution of 3.5 meV for energies in a few hundred meV range. Electron scattering data in O2 suggest an important contribution of the partial waves l=4 and 6 which should give rise to rotational excitation of the molecule. Work in progress on electron scattering in NO and on vibrational excitation of the (100) and (001) modes near threshold in CO2 benefits from the improved resolution
