摘要：

The dependence of the electronic stopping powers on the incident ions of the atomic number Z(1) in the materials of carbon, aluminum, nickel, silver and gold has been evaluated by using the new Firsov formula included the Sugiyama potential for the Firsov model and the screening length with the shell effect of electrons. It was found that the calculated results based on the new Firsov formula show the experimentally well-known Z(1)-oscillation in the electronic stopping powers. The electronic stopping powers measured in carbon, aluminum, nickel and silver are reasonably reproduced by the new Firsov formula for the ZBL potential. (C) 2009 Elsevier B.V. All rights reserved.
