The stopping power of Mo, Cr, Cu and Ni for He ions at velocities belo
w the Bohr velocity has been studied. The stopping power values were d
educed by comparing ranges of 5-100 keV He+-ions determined with the e
lastic-recoil-detection-analysis (ERDA) method with those obtained in
molecular dynamics simulations. The nuclear slowing down was treated t
hrough the use of molecular dynamics calculations and a potential obta
ined from density-functional theory calculations. The comparisons of t
he range profiles showed that the electronic stopping powers given by
J.F. Ziegler, J.P. Biersack and U. Littmark (The Stopping Powers and R
anges of Ions in Matter, vol, 1, Pergamon press, New York, 1985) had t
o be multiplied with a factor of 1.20 +/- 0.07 for Mo and Cr and 1.00
+/- 0.06 for Cu and Ni. (C) 1998 Elsevier Science B.V. All rights rese
