D069800100013 MONITOR (13-AL-27(D,X)11-NA-24,,SIG) D069800100014 MONIT-REF (B0142004,U.Martens+,R,KFK-1083,1969) D069800100015 METHOD (EXTB,STTA,ACTIV) D069800100016 ERR-ANALYS (DATA-ERR) The errors in the measured cross sections D069800100017 arise in the determination of the product nuclide D069800100018 activity and of the deuteron flux. D069800100019 The gamma-ray yield involves the photopeak counts, the D069800100020 photopeak efficiency of the detector, the gamma-ray D069800100021 transition probability, the internal conversion D069800100022 correction and a correction for the self-absorption D069800100023 in the sample. D069800100024 In the determination of the isomer ratios, errors in D069800100025 beam intensity, target thickness and target D069800100026 uniformity cancel. D069800100027 The only errors affecting these ratios are counting D069800100028 errors. D069800100029 STATUS (TABLE) Table 1 of Radiochem.
