The isotopic composition of 234U, 235U, 236U D036200100012 and 238U in the uranium targets was approx. 0.001%, D036200100013 0.047%, 99.845% and 0.107%, respectively. The average D036200100014 thickness of the 236U layer was 100 mu-g/ cm2 and the D036200100015 variations in the thickness were within 3%. Seven D036200100016 uranium targets were placed in the multiple target D036200100017 system D036200100018 METHOD (ACTIV) D036200100019 DECAY-DATA The decay parameters were taken from Firestone, R.B., D036200100020 ERR-ANALYS (ERR-1) The variations in the thickness D036200100021 STATUS (TABLE) Table 1 from Radiochim.Acta,93(2005)377 D036200100022 HISTORY (20051017C) SD D036200100023 (20190820A) SD: Subents 005, 006 deleted (Yields D036200100024 derived from the excitation functions of own D036200100025 experiments + literature).
