Excitation of Atoms by Electron Impact
1979Publisher Summary This chapter points out some of the major advances that have been made in the past decade. The chapter treats a particular area where technical advance or improved understanding has made possible measurements that in many cases must be regarded as definitive.

Excitation of helium by electron impact
Journal of Applied Physics, 1981A simple analytic central potential with two adjustable parameters is proposed for the helium atom. The potential parameters are obtained by appealing to the precise values of optical oscillator strengths calculated by Schiff et al. Using the Born approximation we calculate 1 1S–n 1P electron-impact excitation cross sections up to 5 keV. Good agreement

Threshold electron impact excitation
2011Threshold 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
