Each sample was sandwiched between 3277300100015 two monitor aluminum (99.99% purity and about 3 um 3277300100016 thickness) foils. 3277300100017 DETECTOR (HPGE) High efficiency HPGe detector with a relative 3277300100018 efficiency of about 68% and an energy resolution of 3277300100019 1.7 keV (FWHM) at 1.33 MeV. The detection efficiency 3277300100020 was calibrated by the standard sources 60Co, 109Cd, 3277300100021 137Cs, 152Eu, 226Ra, and 241Am. 3277300100022 METHOD (ACTIV) Irradiating time was about 240 min. The 3277300100023 samples were placed at 0, 45 and 90 deg angles 3277300100024 relative to the deuterium beam direction and centered 3277300100025 about the T-Ti target at distance of 4.0 cm. 3277300100026 (GSPEC) Off-line gamma-ray spectrometry 3277300100027 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3277300100028 M.B.Chadwick+,ENDF/B-VIII.b5,2011 3277300100029 CORRECTION Corrected for 3277300100030 - neutron flux fluctuation (K), 3277300100031 - geometry (Fg), 3277300100032 - coincidence sum effect (Fc), 3277300100033 - gamma self-absorption (Fs). 3277300100034 ERR-ANALYS (ERR-T) The uncertainties mainly came from the 3277300100035 detection efficiency and statistical uncertainty of 3277300100036 counts of the full-energy gamma-ray peaks, and also 3277300100037 including the other parts: correction factor F, 3277300100038 neutron flux fluctuation factor K, decay constant, 3277300100039 mass and corresponding geometric conditions. 3277300100040 (ERR-1) Detection efficiency was about 2.0% 3277300100041 STATUS (TABLE) Table 3 of Appl.Radiat.Isot.132(2018)61 3277300100042 HISTORY (20191217C) Compiled by LI Xiaojun (LanZhou Univ.) 3277300100043 (20211103U) On.
