C236500100011 DETECTOR (GELI) C236500100012 METHOD (ACTIV,CHSEP) Chemical separations were carried out C236500100013 on all of the targets. The gamma radiations of the C236500100014 four isotopes of interest were determined with a C236500100015 calibrated Ge(Li) detector at a low geometry so that C236500100016 the loss of counting rate in the photopeak due to C236500100017 summing with coincident radiation was negligible. The C236500100018 decay of each nuclide was followed for a minimum of C236500100019 two half-lives. C236500100020 ANALYSIS (DECAY) The decay curves were analyzed by a C236500100021 least squares computer program in order to obtain the C236500100022 activities and their standard deviations at end-of- C236500100023 bombardment time. C236500100024 ERR-ANALYS (ERR-T) The error estimates given for the mean C236500100025 values were obtained by root-mean-square addition of C236500100026 these individual errors and of the standard deviation C236500100027 of the mean. C236500100028 (ERR-1) Counting efficiencies. C236500100029 (ERR-2,0.7,1.5) Recoil losses. C236500100030 (ERR-3) Secondary production of 24Na. C236500100031 CORRECTION Since relatively thin target foils were used in these C236500100032 experiments (65 to 97 mg/cm2), it was necessary to C236500100033 correct all measured cross sections for recoil losses.
