The gas 1435200100018 cell was placed at the center of the GEANIE array, 1435200100019 with the neutron beam passing through the Kapton 1435200100020 foils. The natNe gas pressure was maintained at 3.96 1435200100021 atm with less than 1% variation over the course of 1435200100022 the experiment. 1435200100023 DETECTOR (HPGE) Gamma rays produced in neutron induced 1435200100024 reactions were measured with the the GErmanium Array 1435200100025 for Neutron Induced Excitations (GEANIE). GEANIE 1435200100026 comprises 20 high-purity germanium detectors with 1435200100027 bismuth germinate (BGO) escape suppression shields. 1435200100028 Detectors have either a planar or coaxial geometry. 1435200100029 (IOCH)The neutron flux on target was measured with an 1435200100030 in-beam fission ionization chamber with 235U and 238U 1435200100031 foils located about 2 m upstream from the center of 1435200100032 the GEANIE array. 1435200100033 INC-SOURCE (SPALL) Pulsed neutron beam was produced via spallation1435200100034 on a natW target by an 800-MeV proton linear 1435200100035 accelerator beam. 1435200100036 METHOD (TOF)The proton beam structure contained 625-ms-long 1435200100037 macropulses repeated at 60 Hz, or every 16.7 ms. 1435200100038 One in three macropulses was delivered to another 1435200100039 facility, resulting in an average rate of pulses/s. 1435200100040 Each macropulse consisted of micropulses spaced 1435200100041 every 1.8 micro-s, each less than 1 ns long. The pulsed1435200100042 beam allowed incident neutron energies to be 1435200100043 determined using the time-of-flight technique. 1435200100044 ERR-ANALYS (DATA-ERR) No information given 1435200100045 HISTORY (20130109C) Compiled by S.H. 1435200100046 ENDBIB 44 0 1435200100047 NOCOMMON 0 0 1435200100048 ENDSUBENT 47 0 1435200199999 SUBENT 14352002 20130109 13871435200200001 BIB 2 2 1435200200002 REACTION (10-NE-20(N,INL)10-NE-20,PAR,SIG,G) 1435200200003 STATUS (TABLE)Data taken from tab. 1 of the reference 1435200200004 ENDBIB 2 0 1435200200005 COMMON 2 3 1435200200006 E LVL-INI 1435200200007 KEV KEV 1435200200008 1633.7 1633.7 1435200200009 ENDCOMMON 3 0 1435200200010 DATA 4 19 1435200200011 EN EN-RSL DATA DATA-ERR 1435200200012 MEV MEV B B 1435200200013 1.9 0.1 0.10 0.01 1435200200014 2.1 0.1 0.30 0.03 1435200200015 2.4 0.1 0.44 0.04 1435200200016 2.7 0.2 0.63 0.06 1435200200017 3.0 0.2 0.44 0.04 1435200200018 3.4 0.2 0.65 0.06 1435200200019 3.8 0.2 0.50 0.05 1435200200020 4.2 0.2 0.45 0.04 1435200200021 4.7 0.3 0.44 0.04 1435200200022 5.3 0.3 0.51 0.05 1435200200023 6.0 0.3 0.50 0.05 1435200200024 6.7 0.4 0.64 0.06 1435200200025 7.5 0.4 0.63 0.06 1435200200026 8.4 0.5 0.60 0.06 1435200200027 9.5 0.5 0.47 0.05 1435200200028 10.6 0.6 0.45 0.04 1435200200029 11.9 0.7 0.39 0.04 1435200200030 13.4 0.7 0.35 0.04 1435200200031 15.0 0.8 0.29 0.03 1435200200032 ENDDATA 21 0 1435200200033 ENDSUBENT 32 0 1435200299999 SUBENT 14352003 20130109 13871435200300001 BIB 2 2 1435200300002 REACTION (10-NE-22(N,INL)10-NE-22,PAR,SIG,G) 1435200300003 STATUS (TABLE)Data taken from tab. 2 of the reference 1435200300004 ENDBIB 2 0 1435200300005 COMMON 2 3 1435200300006 E LVL-INI 1435200300007 KEV KEV 1435200300008 1274.5 1274.5 1435200300009 ENDCOMMON 3 0 1435200300010 DATA 4 18 1435200300011 EN EN-RSL DATA DATA-ERR 1435200300012 MEV MEV B B 1435200300013 1.5 0.1 0.08 0.01 1435200300014 1.7 0.1 0.41 0.04 1435200300015 1.9 0.1 0.57 0.05 1435200300016 2.1 0.1 0.48 0.04 1435200300017 2.4 0.1 0.61 0.06 1435200300018 2.7 0.2 0.56 0.05 1435200300019 3.0 0.2 0.82 0.09 1435200300020 3.4 0.2 0.90 0.09 1435200300021 3.8 0.2 0.74 0.07 1435200300022 4.2 0.2 1.06 0.11 1435200300023 4.7 0.3 0.87 0.10 1435200300024 5.3 0.3 1.01 0.13 1435200300025 6.0 0.3 0.99 0.11 1435200300026 6.7 0.4 1.20 0.15 1435200300027 7.5 0.4 1.21 0.18 1435200300028 8.4 0.5 1.13 0.15 1435200300029 9.5 0.5 1.07 0.12 1435200300030 10.6 0.6 1.04 0.12 1435200300031 ENDDATA 20 0 1435200300032 ENDSUBENT 31 0 1435200399999 ENDENTRY 3 0 1435299999999
