Abstract

A study of **4He backscattering (150 degree ) cross sections for O, Al, and Si atoms in the energy range 0. 6-2. 3 MeV has been completed. We conclude that the **4He backscattering cross section for these elements follows the E** minus **2 energy dependence of Rutherford backscattering to 1%-2% over this energy range. These results have significant implications for the use of **4He backscattering as a materials analysis tool for low-Z elements.
