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.
