C195500100010 SAMPLE (82-PB-208,ENR=0.9914) Several enriched 208Pb targets C195500100011 with thickness of 10 - 200 mg/cm2 were used C195500100012 DETECTOR (SIBAR) Several Si surface barrier detectors with C195500100013 efficiencies of 7 - 15 % were used to measure alpha C195500100014 activity of product nucleus 211At. C195500100015 METHOD (ACTIV,RCHEM) Activation method was used. Samples C195500100016 irradiated for periods from 2 to 8 hours were C195500100017 radiochemically separated and their alpha activity C195500100018 determined. The radiochemical yields were C195500100019 typically 35 %. C195500100020 ANALYSIS Two alpha decay branches at energies of 5.87 and C195500100021 7.45 MeV were measured, final result is the average C195500100022 value of both measurements C195500100023 ERR-ANALYS (ERR-T) Total uncertainty C195500100024 (ERR-S,15.0,30.0) Statistical uncertainty C195500100025 (ERR-1) Systematic uncertainty in chemical separation C195500100026 efficiency C195500100027 (ERR-2) Systematic uncertainty in detection efficiency C195500100028 (ERR-3) Syst. uncertainty in beam current determinationC195500100029 (ERR-4) Systematic uncertainty in target thickness C195500100030 HISTORY (20121102C) Compiled by S.H.
