Abstract

The stopping power of Mo, Cr, Cu and Ni for He ions at velocities below the Bohr velocity has been studied. The stopping power values were deduced by comparing ranges of 5-100 keV He+-ions determined with the elastic-recoil-detection-analysis (ERDA) method with those obtained in molecular dynamics simulations. The nuclear slowing down was treated through the use of molecular dynamics calculations and a potential obtained from density-functional theory calculations. The comparisons of the range profiles showed that the electronic stopping powers given by J.F. Ziegler, J.P. Biersack and U. Littmark (The Stopping Powers and Ranges of Ions in Matter, vol. 1, Pergamon press, New York, 1985) had to be multiplied with a factor of 1.20 ± 0.07 for Mo and Cr and 1.00 ± 0.06 for Cu and Ni.
