ELECTRON-MOLECULE COLLISION CROSS SECTIONS IN HELIUM AND ARGON MEASURED BY A TIME-OF-FLIGHT TECHNIQUE.
Abstract
The total collision cross sections of helium and argon for electrons of very low energy have been measured by a new technique employing time-of-flight velocity selection. The present measurements extend below 200 mev; the ultimate limit of the technique is about one decade lower. Helium shows a 6 sq A cross section, decreasing monotonically below 400 mev with no structure. The argon cross section falls from 1.6 sq. A at 1 volt to a minimum of 0.4 sq. A at 300 mev, and then rises steeply. (Author)
