The precursor 3079200100027 contribution to the Sb-128-m activity was found to vary3079200100028 between 77% and 86%, depending upon separation time. 3079200100029 INC-SPECT Thermal neutron spectrum 3079200100030 ERR-ANALYS The values given are mean of three or more measurements3079200100031 The error on an individual measurement is the compoun- 3079200100032 ded error due to counting statistics, uncertainties in 3079200100033 abundances of gamma lines, the fractional cumulative 3079200100034 yield of Sn-128, the irradiation and separation times 3079200100035 and half lives. 3079200100036 CORRECTION The contribution from 3.6% internal-transition decay of3079200100037 Sb-128-m was found to be within the experimental error 3079200100038 on the isomeric yield ratios and hence was not 3079200100039 considered. 3079200100040 HISTORY (19920406C) HW 3079200100041 (19920617A) HW, MISPUNCH IN REACTION DEFINITION IN 3079200100042 SUBENTRY 002 CORRECTED. 3079200100043 (20060712A) Date format and ref. corrected 3079200100044 STATUS DATA ARE TAKEN FROM TABLE 1 OF Z.PHYS.
