The three 3280900100014 samples were installed at ~3.5 cm from the T-Ti 3280900100015 target and at 0 deg, 45 deg and 90 deg relative to 3280900100016 the incident deuteron beam. 3280900100017 INC-SOURCE (D-T) 3280900100018 DETECTOR (HPGE) The gamma-ray activity of samples was measured 3280900100019 with a well calibrated HPGe-gamma detector. The 3280900100020 HPGe-gamma detection system has an energy resolution 3280900100021 of 1.7 keV FWHM at 1.33 MeV. The calibration of 3280900100022 energy and efficiency was carried out by the 3280900100023 standard: 241Am, 60Co, 137Cs and 152Eu. A 3280900100024 recalibration was performed also for the dead time, 3280900100025 because of the high activities in the irradiated 3280900100026 samples due to large number of fission nuclides. The 3280900100027 correction between software output and count loss 3280900100028 from the HPGe-gamma system was re-estimated with a 3280900100029 jamming gamma-source (137Cs). 3280900100030 MONITOR
