C3039001 13 DETECTOR (HPGE) High purity germanium gamma-ray detector C3039001 14 (Canberra, model GC3518) surrounded by lead shielding.C3039001 15 SAMPLE Thin, vacuum-deposited natGe targets (0.41+-0.02 micromC3039001 16 natGe on 25.4 microm Kapton) were purchased from AstraC3039001 17 Technology Unlimited, Inc. Nickel (15.6+-0.4 microm C3039001 18 natNi, 99.9%) and aluminum (52.7+-0.4 microm natAl, C3039001 19 99.0%) foils were purchased from Goodfellow Cambridge C3039001 20 Ltd. C3039001 21 METHOD (ACTIV,STTA) C3039001 22 ANALYSIS Cross sections were calculated from the activation C3039001 23 equation for thin foils. After the AEOB was obtained C3039001 24 from HPGe, the cross section is sigma=AEoB/(I*n*x*(1 - C3039001 25 exp(-lambda*tirrad))), where I is the number of C3039001 26 incident particles per unit time, n is the target C3039001 27 nuclei per unit volume, x is the target thickness, C3039001 28 lambda is the radionuclide decay constant, and tirrad C3039001 29 is the irradiation time. C3039001 30 ERR-ANALYS (ERR-T) All uncertainties in this work correspond to C3039001 31 values within one standard deviations of the mean. C3039001 32 The uncertainty in measured radionuclide activities C3039001 33 was calculated by the standard deviation of the C3039001 34 activities measured in each of several HPGe C3039001 35 measurements. These standard deviations are larger C3039001 36 than the uncertainties calculated by error C3039001 37 propagation of individual activity uncertainties, C3039001 38 resulting in overall EoB 71As activity uncertainties C3039001 39 of 2-11%. The uncertainties of counting (0.3-11%) , C3039001 40 foil thickness (3.6%), abundance (2.7%) , detector C3039001 41 efficiency (2.2-2.6%), and beam intensity (3-11%) C3039001 42 were considered for the uncertainty of cross section C3039001 43 measurements by error propagation.
