Absolute differential cross sections for scattering of 0.5-, 1.5-, and 5.0-keV H and He atoms by H/sub 2/ and N/sub 2/ over the laboratory angular range 0.05/sup 0/--0.5/sup 0/ are reported. Charged collision products are not detected, and no determination is made of the energy loss experienced by the scattered projectile. The measured cross sections therefore include both inelastic and elastic processes. The data are in excellent accord with previous measurements of these processes at larger angles. The data have been integrated over angle to permit comparison with other experimental data.
