The energy dependence of the total differential scattering cross-section of 20-180 keV H{sup +}, D{sup +} and He{sup +} ions, as well as 100-350 keV C{sup ++} and O{sup ++} ions, backscattered through a laboratory angle of 161.2{degree} by monolayer-thick Au targets was measured. The ratio of the measured cross section to the Rutherford cross section ranged from 0.91 for 180 keV H{sup +} to 0.44 for 100 keV O{sup ++}. The results were found to be in excellent agreement with exact classical calculations of the scattering cross section performed using Dirac-Fock atomic potentials. A comprehensive review of all previous measurements of the screened Rutherford backscattering cross section has been performed for comparison with the present results.
