A solid tritium- 3165400100016 titanium (T-Ti) target with 2.18 mg/cm2 thickness 3165400100017 was used. 3165400100018 SAMPLE High-purity GeO2 (99.99%)of natural isotopic 3165400100019 composition was pressed into 20 mm diameter and 3165400100020 2.5-3.9 mm thickness slice. Each Germanium sample 3165400100021 was sandwiched between two Al foils, and the purity 3165400100022 of the Al foils is better than 99.99%. 3165400100023 DETECTOR (HPGE)coaxial HPGe detector (ORTEC, made in USA) 3165400100024 with a relative efficiency of 68% and an energy 3165400100025 resolution of 1.69 keV FWHM at 1.33 MeV. 3165400100026 METHOD (GSPEC)The radioactivity of each investigated 3165400100027 product was determined via the gamma-ray spectroscopy 3165400100028 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3165400100029 DECAY-MON (11-NA-24,14.959HR,DG,1368.633,1.) 3165400100030

( 2%), 3165400100034 (ERR-2) neutron energy and fluency uncertainties (2.5%)3165400100035 mass of the samples (<0.1%), self-absorption of 3165400100036 gamma-rays (0.5%), the irradiation, cooling and 3165400100037 measuring times (<0.8%)etc. 3165400100038 The total uncertainty was obtained by the combination 3165400100039 of all the individual uncertainties in quadrature. 3165400100040 HISTORY
