Abstract
ON the ionisation of gases by particles of atomic mass (ions and atoms) very few results have been obtained hitherto. As regards neutral atoms with moderate energy (less than 1,000 electron-volts), the only available data are those referring to the effective cross-sections for ionisation of argon by argon atoms with 500 and 650 e.v. energy, as determined lately by O. Beeck and H. Wayland1; earlier work by Beeck and by C. J. Brasefield2 being of a rather qualitative character, and their results uncertain.
