Cross sections for 165° backscattering of 4He ions from Na and AI films at energies in the range of 2.0-6.0 MeV have been measured. The cross sections were measured with a maximum interval of 50 keV and typical uncertainties of ±2.5%. Experimental results show that
for sodium and aluminum the upper energies at which the backscattering cross section can still be predicted by Rutherford scattering formula
are3.0 MeV and 3.5 MeV
respectively. When energe is higher than the upper value
the backscattering cross section shows a continuous nuclear resonance distribution both for sodium and for aluminum.
