This paper reports measurements of absolute cross sections, differential in ange, for scattering of 0.5/sup -/, 1.5/sup -/, and 5.0/sup -/keV hydrogen atoms by He, H/sub 2/, and O/sub 2/ at laboratory scattering angles between 0.1/sup 0/ and 5/sup 0/. The measured cross sections are the sums of those for elastic and inelastic collisions having a fast H atom product and are needed for calculating energy transfer to the upper atmosphere from precipitating ring current particles.
