Absolute measurements of the total single-electron detachment (SED) cross sections [sigma][sub [minus]10] for 3--50-keV H[sup [minus]] ions incident on helium atoms and for 5--50-keV H[sup [minus]] ions incident on neon and argon atoms are reported in this paper. The present SED cross sections for helium and neon targets are of similar magnitude but have a different energy dependence. By contrast, the SED cross sections for argon targets are significantly larger than either of the other two target species reported in this paper. Comparisons are made with the previous measurements and calculations in the literature.
