The purity of the Al metal was better than 3270100100014 99.99%. 3270100100015 DETECTOR (HPGE) A well-calibrated GEM-60P coaxial high-purity 3270100100016 germanium (HPGe) detector was used with 70.1x72.3 mm 3270100100017 in diameter and length for the crystal, respectively. 3270100100018 The relative efficiency was about 68%, and the energy 3270100100019 resolution was about 1.69 keV (FWHM) at 1.33 MeV. 3270100100020 METHOD (ACTIV,GSPEC) Irradiation of the samples was carried 3270100100021 out and lasted 15 min with a neutron yield of about 3270100100022 3E10 to 5E10 n/s. 3270100100023 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3270100100024 DECAY-MON (11-NA-24,14.997HR,DG,1368.626,0.999936) 3270100100025 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,,1990) 3270100100026 The cross section values of the monitor reaction were 3270100100027 obtained by interpolating the evaluated work of the 3270100100028 literature. 3270100100029 INC-SOURCE (D-T) The solid tritium-titanium (T-Ti) target was 3270100100030 used with 2.4 mg/cm2 in thickness. 3270100100031 ERR-ANALYS (ERR-T) Total uncertainty of measurement. 3270100100032 (ERR-S,,1.) Statistical uncertainties. 3270100100033 (ERR-1) Uncertainty of detector efficiency. 3270100100034 (ERR-2,,2.) Uncertainty of the coincidence sum effect 3270100100035 of cascade gamma-ray. 3270100100036 (ERR-3,,0.5) Uncertainty of sample weights and self- 3270100100037 absorption of gamma-ray. 3270100100038 (ERR-4,,0.5) Uncertainties from irradiation, cooling 3270100100039 and measurement time. 3270100100040 (MONIT-ERR) Uncertainty of monitor cross section. 3270100100041 CORRECTION Dead-time and pulse pileup corrections were less than 3270100100042 2% in all cases. While determining the activities of 3270100100043 the gamma-rays, corrections for self-absorption of 3270100100044 the gamma-rays, real coincidence summing and geometry 3270100100045 were made. 3270100100046 COMMENT In Table 1, the half-life of 52V was 3.743 month. The 3270100100047 author confirmed that it must be 3.743 min. 3270100100048 STATUS (TABLE) Table 2 of Rad.Phys.Chem.81(2012)1563 3270100100049 HISTORY (20120906C) Compiled by Jimin WANG (CNDC). 3270100100050 (20180419U) On.
