At the lower neutron 1351800100024 energies, an estimated systematic uncertainty of 5% 1351800100025 is the dominating uncertainty. 1351800100026 (ERR-SYS) Systematic uncertainty 1351800100027 STATUS (APRVD) L.W.Weston, 1991/11/6 1351800100028 (TABLE) Data taken from Table 1 in NSE,109,113,1991 1351800100029 HISTORY (19911028C) 1351800100030 (20120711A) SD:Updated to new date formats,lower case. 1351800100031 Corrected according to last EXFOR rules and Dict. 1351800100032 ENDBIB 30 0 1351800100033 COMMON 1 3 1351800100034 ERR-SYS 1351800100035 PER-CENT 1351800100036 5.0 1351800100037 ENDCOMMON 3 0 1351800100038 ENDSUBENT 37 0 1351800199999 SUBENT 13518002 20120711 13841351800200001 BIB 2 3 1351800200002 REACTION ((5-B-10(N,A)3-LI-7,PAR,SIG)// 1351800200003 (5-B-10(N,A)3-LI-7,PAR,SIG)) 1351800200004 HISTORY (20120711A) SD: Value of E-LVL-DN was corrected. 1351800200005 ENDBIB 3 0 1351800200006 COMMON 2 3 1351800200007 E-LVL-NM E-LVL-DN 1351800200008 KEV KEV 1351800200009 0. 478. 1351800200010 ENDCOMMON 3 0 1351800200011 DATA 3 25 1351800200012 EN DATA ERR-T 1351800200013 KEV NO-DIM NO-DIM 1351800200014 20. 0.064 0.004 1351800200015 45. 0.062 0.004 1351800200016 85. 0.066 0.005 1351800200017 120. 0.055 0.005 1351800200018 160. 0.067 0.006 1351800200019 200. 0.087 0.008 1351800200020 240. 0.078 0.008 1351800200021 280. 0.097 0.010 1351800200022 320. 0.132 0.014 1351800200023 360. 0.146 0.015 1351800200024 400. 0.182 0.019 1351800200025 440. 0.160 0.018 1351800200026 480. 0.251 0.026 1351800200027 520. 0.244 0.026 1351800200028 560. 0.311 0.034 1351800200029 600. 0.278 0.033 1351800200030 640. 0.390 0.046 1351800200031 680. 0.399 0.058 1351800200032 720. 0.343 0.053 1351800200033 760. 0.437 0.081 1351800200034 800. 0.525 0.114 1351800200035 840. 0.463 0.090 1351800200036 880. 0.461 0.102 1351800200037 920. 0.715 0.151 1351800200038 960. 0.678 0.145 1351800200039 ENDDATA 27 0 1351800200040 ENDSUBENT 39 0 1351800299999 ENDENTRY 2 0 1351899999999
