A beam current ~ 100 nA was monitored from D600800100013 current integrator count rate. D600800100014 ERR-ANALYS (ERR-1) The error due to efficiency < 3%, D600800100015 (ERR-2) The error due to foil thickness < 5%, D600800100016 (ERR-3) The error due to nonuniformity of foil < 1%, D600800100017 (ERR-4) The error due to fluctuations in beam D600800100018 current < 3%. D600800100019 (ERR-T) The overall error due to all these (ERR-1 D600800100020 till ERR-4) factors plus uncertainties in the D600800100021 in the branching ratio , decay constants and half-livesD600800100022 Overall error due to all these factors is expected D600800100023 to be < 15%. D600800100024 METHOD (ACTIV)Activation D600800100025 DETECTOR (GELI) The activities induced in various sample D600800100026 foils were recorded using a Ge(Li) detector, which D600800100027 was pre-calibrated using various standard D600800100028 gamma-sources.
