Electron Impact Excitation of CO .

Extensive differential cross-sections for the electron impact excitation of CO for electronic states from 6eV to 1.5eV are presented. The data were taken for electron scattering angles from 10$^{\mathrm{o}}$ to 120$^{\mathrm{o}}$ and impact energies from 6.1eV to 20eV. The data were obtained by unfolding the energy loss spectra of CO taken t these energies and scattering angles.
