D407500100011 Isot. 46,1413,1995 D407500100012 FACILITY (CYCLO,3HUNDEB) D407500100013 (CYCLO,2GERJUL) D407500100014 SAMPLE the target used were natural argon gas of 1 bar D407500100015 pressure in stainless steel cells with 10 micron D407500100016 Ti windows. D407500100017 DETECTOR (HPGE) D407500100018 METHOD (ACTIV,STTA,GSPEC) single and stacked cells were D407500100019 irradiated with extracted alpha beam at 500 Na beam D407500100020 current. The bombarding charge was integrated by a D407500100021 Faraday-cup and was also monitored via monitor D407500100022 reactions on copper. The single cell irradiations D407500100023 were carried out at the debrecen mgc20 cyclotron, D407500100024 and the stacked cells were irradiated at the Julich D407500100025 CV28 compact cyclotron using 20.4 And 26.7 MeV primary D407500100026 beam energy respectively. D407500100027 ANALYSIS (AREA) normal high resolution gamma-spectrometry D407500100028 was applied. Nuclear data were taken from E. Browne D407500100029 and R.B.Firestone, Table of Radioactive Isotopes, D407500100030 edited by V.S shirley, Wiley, New York, 1986. D407500100031 the energy degradation was calculated using the D407500100032 tables of williamson et al.,Report, CEA-R-3042 and D407500100033 J.F. Ziegler Handbook of stopping cross sections for D407500100034 energetic ions in all elements, vol.5, Pergamon,Oxford,D407500100035 1980. D407500100036 ERR-ANALYS (EN-ERR) the error of the energy includes the D407500100037 primary dispersion of the incident beam, the D407500100038 uncertainty by the straggling effect and the density D407500100039 reduction in the gas cells along the beam strike. D407500100040 the typical uncertainty of the energy is about 1. MeV D407500100041 near the threshold and 0.3 MeV around 20 MeV. D407500100042 (ERR-T) the overall error in the cross section D407500100043 determination includes the errors: D407500100044 flux measurements 8% D407500100045 statistical error 1-5% D407500100046 detector efficiency error 5% D407500100047 nuclear data uncertaintty 3% D407500100048 effective target thickness 5% D407500100049 total estimated error in the cross section values was D407500100050 about 12%.
