Threshold electron impact spectra have been obtained for helium, neon, argon, krypton, xenon and carbon monoxide using a velocity-selected electron beam. Zero energy electrons ejected at excitation thresholds are scavenged by sulfur hexafluoride and the resulting SF(6)¯ ions are detected using a mass filter. Optically forbidden transitions are observed to make a large contribution to the total threshold excitation. Singlet-triplet transitions are especially prominent in helium and carbon monoxide. Excitation of outer s and p electrons is observed for neon, argon, krypton and xenon. / Science, Faculty of / Chemistry, Department of / Graduate
