Abstract
The energy dependence of the total differential scattering cross section of 20–180 keV H +, D + and He + ions, as well as 100–350 keV C 2+ and O 2+ ions, backscattered through a laboratory angle of 161.2° 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 4 to 0.44 for 100 keV O 2+. 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.
