Be is an important element in fusion and fission reactor technology and in X-ray optical components. Non-Rutherford backscattering is desirable when the stoichiometry and depth profile of Be and other heavy elements have to be measured simultaneously. Cross sections for {theta}{sub lab}=165{degrees} of He-ion backscattering on Be in the 0.5 - 5.3 MeV energy range were measured. Self-supported films of 15 {mu}g/cm{sup 2} Be were used as targets. The measured resonance at 5.05 MeV shows a cross section 102 times as large as the Rutherford cross section. The cross sections are presented in graphic and tabular forms with 2% uncertainty.
