Absolute differential cross sections are reported for collisions between 0.5, 1.5, and 5.0-keV-energy H atoms and He, Ne, Ar, Kr, and Xe over the laboratory-frame angular range 0.018{degree}--0.5{degree}. The scattered neutral particles are detected, and the measured cross sections include both elastic and inelastic events. The H-He results are in excellent accord with previous measurements at larger angles. Empirical interaction potential-energy curves have been extracted from the data for all collisions studied.
