Abstract
WE have reported recently the results of a series of measurements of the electron loss cross-section for hydrogen atoms of 5–40 keV. energy in various gases1,2. The method employed is capable of some precision, and the cross-sections obtained are accurate, we believe, to within 2–3 per cent. As a result we have been able to determine that in hydrogen and in carbon monoxide the cross-section does not vary smoothly with energy, but has a number of large fluctuations. In the carbon monoxide cross-section, for example, there are nine maxima in the region 8–40 keV. The magnitude of the oscillations is of the order of 10−16 cm.2 in a total cross-section of the order of 1–5 × 10−16 cm.2.
