The ion beam S024000100011 energy at 1.0 MeV, the energy dispersion was less S024000100012 than 2 keV. S024000100013 SAMPLE The experimental target was made of graphite S024000100014 substrate. Purity of 99 99% of silicon was evaporated S024000100015 on the carbon substrate, and then 99.99% pure gold S024000100016 was evaporated on the silicon film. The thickness of S024000100017 silicon target and gold film obtained from 4He S024000100018 backscatter analysis were 4.7E8 and 2.4E17 atoms/cm2. S024000100019 METHOD The measurement angle was 160 deg. The beam was S024000100020 collimated through two apertures spaced 1.5 meters S024000100021 apart. The spot area on the target was 0.7mm *0.7 mm. S024000100022 The detection solid angle was 0.48 +- 0.01 msr. S024000100023 DETECTOR (SIBAR)The detector energy resolution was 12 keV. The S024000100024 gold silicon surface barrier detector energy S024000100025 spectrometer was used to measure the backscatter S024000100026 energy spectrum of each energy point.
