Thus, 2376600100015 they impinged on the solid Ti-tritiated target with 2376600100016 the desirable(lower) energy. 2376600100017 SAMPLE The 234U and 238U samples are thin 5 um disks with a 2376600100018 2.6 cm radius deposited on a 100 um Al-backing. 2376600100019 The impurities were found to be much less than 1 % of 2376600100020 the total active mass. 2376600100021 The samples were placed at a distance of 20 cm from the2376600100022 tritium target, thus limiting their angular 2376600100023 acceptance to +- 20 degrees. 2376600100024 DETECTOR (IOCH) A Micromegas detector assembly was used to 2376600100025 record the fission fragments. 2376600100026 MONITOR (92-U-238(N,F),,SIG) 2376600100027 MONIT-REF (,M.B.Chadwick+,3,ENDF/B-VII.1,,2011) 2376600100028 ERR-ANALYS (ERR-S) Statistical uncertainties of the measurements 2376600100029 (ERR-1) Systematic uncertainty of the 234U number of 2376600100030 the target nuclei - 1% 2376600100031 (ERR-2) Systematic uncertainty of the 238U number of 2376600100032 the target nuclei - 2% 2376600100033 HISTORY (20210301C) VS 2376600100034 ENDBIB 32 0 2376600100035 COMMON 2 3 2376600100036 ERR-1 ERR-2 2376600100037 PER-CENT PER-CENT 2376600100038 1. 2. 2376600100039 ENDCOMMON 3 0 2376600100040 ENDSUBENT 39 0 2376600199999 SUBENT 23766002 20210301 22982376600200001 BIB 2 2 2376600200002 REACTION (92-U-234(N,F),,SIG) 2376600200003 STATUS (TABLE) Table 3 of EPJ Web of Conf. 239(2020)05005 2376600200004 ENDBIB 2 0 2376600200005 NOCOMMON 0 0 2376600200006 DATA 5 3 2376600200007 EN EN-RSL-HW DATA ERR-S MONIT 2376600200008 MEV MEV MB MB MB 2376600200009 14.8 0.3 2164. 105. 1221. 2376600200010 16.5 0.3 2489. 81. 1318. 2376600200011 17.8 0.2 2343. 172. 1320. 2376600200012 ENDDATA 5 0 2376600200013 ENDSUBENT 12 0 2376600299999 ENDENTRY 2 0 2376699999999
