Two such pellets were 3273000100013 prepared. Thickness of each sample was determined by 3273000100014 weighing and measuring the diameter of foil, and the 3273000100015 thickness of samples was 0.118 and 0.136 cm. Monitor 3273000100016 foils of Nb (99.99% pure, 0.5 mm thick) and Al 3273000100017 (99.999% pure, 0.3 mm thick) of the same diameter as 3273000100018 the pellets were then attached in front and at the 3273000100019 back of each sample. 3273000100020 INC-SOURCE (D-T) An effective deuteron beam energy of 134 keV 3273000100021 and beam current of 260 uA. The tritium-titanium (T- 3273000100022 Ti) target was 2.38 mg/cm2 thick. 3273000100023 DETECTOR (HPGE) A high-purity germanium (HPGe) detector with a 3273000100024 relative efficiency of 68% and an energy resolution 3273000100025 of 1.69 keV at 1332 keV for 60Co. The distance 3273000100026 between the sample and the detector was about 3-9 cm. 3273000100027 (SIBAR)The Au-Si surface barrier detector used in 135 3273000100028 degree accompanying a-particle tube was at a distance 3273000100029 of 110 cm from the target. 3273000100030 METHOD (ACTIV) Irradiation of the samples was lasted about 2 3273000100031 hours with a yield about 3 to 4E10 n/(4pi*s). The 3273000100032 groups of samples were placed at 0 and 135 degree 3273000100033 angle relative to the beam direction and centered 3273000100034 about the T-Ti target at distances of about 5 cm. 3273000100035 MONITOR 1(13-AL-27(N,A)11-NA-24,,SIG) 3273000100036 2(41-NB-93(N,2N)41-NB-92-M,,SIG) 3273000100037 DECAY-MON 1(11-NA-24,14.959HR,DG,1368.6,1.00) 3273000100038 2(41-NB-92-M,10.15D,DG,934.4,0.9907) 3273000100039 J.Luo (2017-06-13): 3273000100040 T1/2=10.152 d in the article is typo and should read 3273000100041 10.15(2) d which was used in the cross section 3273000100042 calculation. 3273000100043 MONIT-REF (,M.Wagner+,B,PH-DAT,13-5,1990) In the calculations, 3273000100044 the cross sections for the 93Nb(n,2n)92mNb and 3273000100045 27Al(n,a)24Na monitor reactions were obtained by 3273000100046 interpolating the evaluated values of the literature. 3273000100047 CORRECTION Corrections were made for the self-absorption of the 3273000100048 sample at a given gamma-energy, the coincidence sum 3273000100049 effect of cascade gamma-rays in the investigated 3273000100050 nuclide and in the counting geometry. 3273000100051 ERR-ANALYS (ERR-T) Total uncertainty. 3273000100052 (ERR-1,0.1,42.)
