O074600100031 (ERR-T) The Uncertainties Associated with the O074600100032 Uncorrected Cross Sections are Due to the Statistical O074600100033 Fluctuations in the Measurements of the Reaction Rates O074600100034 With Target-In and Target-Out, and the Error AssociatedO074600100035 With the Measurements of the Target Thickness. O074600100036 Reproducibility of the Data was Checked by Taking ThreeO074600100037 Measurements For Each Target at Every Energy During theO074600100038 Experiment. The Corrections to Uncorrected Sigma were O074600100039 Calculated and the Total Error in Sigma Obtained by O074600100040 Adding All Errors in Quadrature.
