The deuteron ion 3288500100013 beam current was up to 180 uA with of an energy of 3288500100014 250 keV. The solid tritium-titanium (T-Ti) target 3288500100015 used in the generator was approximately 2.59 mg/cm2 3288500100016 thick. 3288500100017 SAMPLE About 6 g of ruthenium powder of natural isotopic 3288500100018 composition (purity 99.95%) was pressed into a pellet 3288500100019 (about 20.0 mm in diameter, 1.5 mm in thickness). 3288500100020 Monitor foils of natural niobium foils (purity 3288500100021 99.99%, 0.1 mm in thickness) of the same diameter as 3288500100022 the pellet were attached in the front and at the back 3288500100023 of each ruthenium sample. Three group such samples 3288500100024 were prepared for irradiation and measurement. 3288500100025 METHOD (ACTIV) Irradiation was lasted approximately 17 h. 3288500100026 The samples were cooled about 18 days. 3288500100027 DETECTOR (HPGE) A lead-shielded HPGe detector (ORTEC, USA). 3288500100028 The relative efficiency of the detector was 68%, and 3288500100029 the energy resolution was 1.82 keV (FWHM) at 1.33 MeV 3288500100030 of 60Co. 3288500100031 ADD-RES (DECAY) Half-life of 95mTc = 61.88 +/- 0.22 d 3288500100032 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3288500100033 DECAY-MON (41-NB-92-M,10.15D,DG,934.440,0.9915) 3288500100034 MONIT-REF (41240003,A.A.Filatenkov,R,RI-252,1999) 3288500100035 COMMENT Changlin Lan: The values in Table 6 are not the 3288500100036 partial uncertainties. 3288500100037 ERR-ANALYS (DATA-ERR) The uncertainties in the measured cross- 3288500100038 sections are found in the range of 2.54 - 2.76% 3288500100039 HISTORY (20251127C) Compiled by Xi Tao (CNDC) 3288500100040 ENDBIB 38 0 3288500100041 COMMON 1 3 3288500100042 EN-ERR 3288500100043 MEV 3288500100044 0.2 3288500100045 ENDCOMMON 3 0 3288500100046 ENDSUBENT 45 0 3288500199999 SUBENT 32885002 20251127 20260228 3288500200001 BIB 3 5 3288500200002 REACTION (44-RU-96(N,X)43-TC-95-M,,SIG) 3288500200003 DECAY-DATA ((1.)43-TC-95-M,61.88D,DG,204.117,0.6320) 3288500200004 ((2.)43-TC-95-M,61.88D,DG,582.082,0.3020) 3288500200005 ((3.)43-TC-95-M,61.88D,DG,835.149,0.2660) 3288500200006 STATUS (TABLE,,Yuting Wei+,J,EPJ/A,58,222,2022) Table 7 3288500200007 ENDBIB 5 0 3288500200008 NOCOMMON 0 0 3288500200009 DATA 5 9 3288500200010 EN DATA DATA-ERR DECAY-FLAG MONIT 3288500200011 MEV B B NO-DIM MB 3288500200012 13.85 0.04490 0.00118 1. 454.4 3288500200013 13.85 0.04367 0.00113 2. 454.4 3288500200014 13.85 0.04370 0.00112 3. 454.4 3288500200015 14.30 0.05341 0.00144 1. 459.6 3288500200016 14.30 0.05268 0.00146 2. 459.6 3288500200017 14.30 0.05832 0.00158 3. 459.6 3288500200018 14.72 0.06224 0.00164 1. 457.1 3288500200019 14.72 0.05996 0.00154 2. 457.1 3288500200020 14.72 0.06437 0.00163 3. 457.1 3288500200021 ENDDATA 11 0 3288500200022 ENDSUBENT 21 0 3288500299999 SUBENT 32885003 20251127 20260228 3288500300001 BIB 4 7 3288500300002 REACTION (44-RU-96(N,X)43-TC-95-M,,SIG,,AV) 3288500300003 ANALYSIS Average over the cross sections determined for three 3288500300004 gamma lines 3288500300005 STATUS (TABLE,,Yuting Wei+,J,EPJ/A,58,222,2022) Fig.5 3288500300006 (DEP,32885002) Cross sections determined for three 3288500300007 gamma lines 3288500300008 HISTORY (20251201R) Data received from Changlin Lan 3288500300009 ENDBIB 7 0 3288500300010 NOCOMMON 0 0 3288500300011 DATA 4 3 3288500300012 EN DATA DATA-ERR MONIT 3288500300013 MEV B B MB 3288500300014 13.85 0.45444 0.00599 454.4 3288500300015 14.30 0.45956 0.00631 459.6 3288500300016 14.72 0.45705 0.00559 457.1 3288500300017 ENDDATA 5 0 3288500300018 ENDSUBENT 17 0 3288500399999 ENDENTRY 3 0 3288599999999
