O091500100007 FACILITY (VDG,2SF HLS) O091500100008 (VDGT,2SF HLS) At energies above 2.7 MeV and for O091500100009 obtaining the 10-MeV Si-28 beam the laboratory'S 5 MV O091500100010 EGP-10-II tandem accelerator was used. O091500100011 MONITOR (73-TA-181(P,EL)73-TA-181,,DA) The cross section was O091500100012 assumed as Rutherford cross section. O091500100013 INC-SPECT *En-rsl* the energy resolution of the detection system O091500100014 was typically 12 KeV for protons. O091500100015 DETECTOR (SIBAR) O091500100016 Several ion implanted silicon detectors were placed at O091500100017 laboratory angles of 110-170 degrees. At energies belowO091500100018 2.7 MeV three detectors (25 mm**2,100 mum) and at O091500100019 higher energies two (25 mm**2,300 mum) detectors were O091500100020 used. O091500100021 SAMPLE The helium targets were prepared by implanting 60-KeV O091500100022 He-4 ions in 1.50-mum thick tantalum foils. The O091500100023 resulting helium depth distribution has a mean range ofO091500100024 180 nm and a width of 85 nm. O091500100025 METHOD (MOMIX) O091500100026 ERR-ANALYS (DATA-ERR,6.,7.) The uncertainties in the cross O091500100027 section values, increase from 6% at the low energy O091500100028 and to 7% at the high energy end. These uncertainties O091500100029 result from statistical errors and background O091500100030 subtraction uncertainties in the helium peak area O091500100031 determination and from the uncertainty in the helium O091500100032 content. When comparing the cross sections taken at O091500100033 different energies these relative values are more O091500100034 accurate with an estimated inaccuracy below 3%.
