O086400100014 SAMPLE The two targets consisted of polished pyrolytic O086400100015 graphite with a evaporated aluminium layer with a O086400100016 thickness of about 3.4E+18 Al atoms/cm**2 on top. O086400100017 On top of the aluminium a boron layer with a thickness O086400100018 of 8.2E+17 B-atoms/cm**2 and a gold layer with a O086400100019 thickness of 5.1E+16 Au-atoms/cm**2 were evaporated. O086400100020 The homogeneity of all layers was checked by special O086400100021 experiments and was better than 1%.

O086400100026 (ANG-ERR) The accuracy of scattering angle. O086400100027 (ERR-1) The uncertainty of N(Au)/N(B) ratio, which is O086400100028 major source of data uncertainty. O086400100029 COMMENT - By authors. Because the cross sections are O086400100030 determined relative to the backscattering cross sectionO086400100031 of protons from gold into the same detector, error in O086400100032 the current measurement and a solid angle determinationO086400100033 do not influence the results. O086400100034 CORRECTION Rutherford Cross section for gold was corrected on O086400100035 influence of electron shielding of the gold nuclear O086400100036 charge.
