Proton D503300100007 currents near 4 micro-A with a beam energy resolution D503300100008 of about 600 eV. D503300100009 SAMPLE Si targets were prepared in the isotope separator. A D503300100010 set of three targets was made by collecting 1 keV D503300100011 28Si+,29Si+and 30Si+ions in amounts of 0.6 micro-g/cm2 D503300100012 on 0.4 mm thick tantalum backing.The target thicknessesD503300100013 were 4.6 micro-g/cm2, which corresponds to the D503300100014 thickness of 810 keV probed by 1 MeV protons. The D503300100015 accuracy of the thickness determination is 1%. D503300100016 METHOD (GSPEC) D503300100017 DETECTOR (GELI) The 110 cm**3 germanium-lithium detector with D503300100018 an energy resolution of 1.9 keV at Eg=1.33 MeV and 2.9 D503300100019 keV at Eg=2.6 MeV and with an efficiency of 21.8% was D503300100020 used for gamma detection. The absolute efficiency of D503300100021 the detector was determined in with the calibrated IAEAD503300100022 standard sources and using gamma-rays from reaction D503300100023 27Al(p,gamma)28Si at Ep=992 keV. D503300100024 (SIBAR)An annular silicon surface barrier detector withD503300100025 an active area of 50 mm2 was used for the Ne-C ratios D503300100026 of the targets using backscattering of alpha-particles.D503300100027 It was located at a distance of 8 cm from the target D503300100028 giving a mean scattering angle of 178 degrees. Its D503300100029 resolution was 14 keV at Ealpha=2.0 MeV. D503300100030 (GELI) The 66 cm**3 germanium-lithium detector placed D503300100031 at a fixed position at a distance of 10 cm from the D503300100032 target is used for the angular distribution D503300100033 measurements at angles 0, 30, 45, 60, 90 degrees. D503300100034 CORRECTION Corrections were made for: D503300100035 oxygen contamination - upper limit 1 at.% to Si atoms D503300100036 eccentricity and absorption -less than 2%.
