F148100100012 FACILITY (ISOCY,4RUSKUR) U-150 cyclotron F148100100013 SAMPLE The targets obtained using sedimentation method were F148100100014 mechanically stable and visually uniformly thick F148100100015 layers of thorium dioxide with thicknesses of 7-11 F148100100016 mg/cm2. The applied spot diameter was 20 mm. F148100100017 INC-SOURCE A mean current was 0.1 mu-A, total charge of ~0.3 mu-AhF148100100018 DETECTOR (HPGE) The peak areas of the total absorption of F148100100019 gamma quanta were measured using an ORTEC GEM gamma F148100100020 spectrometer with an ultrapure germanium detector. F148100100021 During the measurements, the targets were located at F148100100022 a distance of 6-40 cm above the detector surface F148100100023 depending on the load of the spectrometer. The dead F148100100024 time during measurements did not exceed 5%. F148100100025 METHOD (ACTIV) The exposure time for each fission fragment F148100100026 significantly exceeded the decay time of its F148100100027 short-lived precursors after the end of irradiation. F148100100028 Therefore, the assumption of complete decay of the F148100100029 precursors by the end of irradiation was made by F148100100030 reducing the measured activity of fission fragments F148100100031 to the end of irradiation. F148100100032 (STTA) The foil stack contained 11 targets. Charged F148100100033 particle moderators in the form of aluminum foils with F148100100034 thicknesses of 9 and 30 mu-m were placed between the F148100100035 targets in the stack. F148100100036 (GSPEC) F148100100037 CORRECTION Calculated corrections for the decay of the F148100100038 radionuclide during the measurement time and F148100100039 self-absorption of gamma-quanta in the targets were F148100100040 introduced. F148100100041 ERR-ANALYS (ERR-T) The errors of the measured values include: F148100100042 (ERR-1,8.,12.) the error in determining the detector F148100100043 efficiency; F148100100044 (ERR-2,10.,15.) the errors in determination of peak F148100100045 areas of the total absorption of gamma quanta in the F148100100046 instrument spectra; F148100100047 (ERR-3,3.,22.) the error of quantum yield.
