O057200100031 The Total Error in the Cross Section Values Given is O057200100032 The Square Root of the Sums of the Squares of the O057200100033 Contributing Errors.The Errors in Determination of the O057200100034 Count Rate at End of Bombardment were Between 2% and O057200100035 9%, Depending on the Individual Case, in Target WeightO057200100036 +-2%, Chemical Yield +-5%,+-10% in Detector EfficiencyO057200100037 Calibration and +-7% in Exact Time of Separation of theO057200100038 Niobium from Its Parent. The Error in During of O057200100039 Bombardment was Negligible and the Beam Spread was O057200100040 +-2 MeV at the Energies Used. The Error Introduced by O057200100041 Neglecting the Time Required For the Decay of the O057200100042 Metastable Isomer to the Ground State was Negligible O057200100043 In the Case of Nb-97 and Less Than 12% For Nb-95.
