Abstract

Direct determinations of the cross sections for single and double electron loss in single collisions by 2-50-keV $H_{1}^{-}$ ions incident upon hydrogen molecules and inert-gas atoms are made by the method of measuring the rate of growth of the fast-collision products, $H_{1}^{0}$ and $H_{1}^{+}$ , with increasing target-gas number density. Previous measurements of $σ_{- 1, 0}$ have included contributions from $σ_{- 1, 1}$ . It is shown that allowance for such contributions is only partially successful in improving the agreement between previously published values.
