Measurements of absolute differential cross sections for direct and charge-transfer scattering of H{sup +} and He{sup +} by the rare gases have been made. Direct scattering cross sections are reported at 1.5 keV for collisions of H{sup +} and He{sup +} with Ne, Ar, Kr, and Xe over the laboratory angular range 0.03{degree}--1.0{degree}. Charge-transfer cross sections are reported for the laboratory scattering angles below 1.0{degree} for H{sup +}-Ar, Kr at 0.5, 1.5, and 5.0 keV, for H{sup +}-Xe at 5.0 keV, and for He{sup +}-Ne at 1.5 keV. The data exhibit a wealth of structure over the experimental angular range, and cross sections have been integrated over angle to provide absolute integral cross sections.
