MONITOR (79-AU-197(P,EL)79-AU-197,,DA) The cross section was O086400100013
assumed as Rutherford cross section. 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%. O086400100022

HISTORY (20010511C) O086400100024
(20030501U) Last checking has been done. O086400100025
ERR-ANALYS (EN-ERR) The accuracy of the incident beam energy. 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. O086400100037
