F1524001 12 SAMPLE (56-BA-136,ENR=0.9545) Thin targets of barium F1524001 13 carbonate enriched by the isotope 136Ba (136Ba-95.45%, F1524001 14 138Ba-2.25%, 137Ba-1.56%, 135Ba-0.75%, 134Ba-0.04%) F1524001 15 were prepared by the sedimentation method. 11 F1524001 16 mechanically stable and visually homogeneous F1524001 17 [136Ba]BaCO3 targets with thicknesses of 2.4-5.8 mg/cm2F1524001 18 were prepared. A cover layer of aluminum foil F1524001 19 (8.4 mu-m) was used. F1524001 20 DETECTOR (HPGE) Gamma spectrometer with an ORTEC GEM 35P4 high F1524001 21 purity germanium with an energy resolution of 850 eV F1524001 22 for the 122 keV line and 1.8 keV for the 1332 keV F1524001 23 line was used. F1524001 24 METHOD (STTA,EDEG) Aluminum degraders (~30, 117, and 44 mu-m) F1524001 25 and copper monitors (~10 mu-m) were placed in a stack F1524001 26 between the targets. F1524001 27 (ACTIV) Irradiation time was 30 min. The first F1524001 28 measurement was carried out 2-5 h after the end of F1524001 29 bombardment; the second measurement was carried out on F1524001 30 the next day. Two measurements were made for each F1524001 31 target foil at calibrated distances of 6 cm and 11.5 F1524001 32 cm. The dead time of measurements did not exceed 10 %.
