It was large enough to cover 1443300100012 entire 5 cm x 5 cm beam spot. 1443300100013 PART-DET (A,N) 1443300100014 DETECTOR (TELES,PROPC,SIBAR) Four two-element detector 1443300100015 telescopes with angular acceptance between 9 and 13 1443300100016 degrees. The front element of each telescope was a 1443300100017 gas proportional counter filled with 25 Torr of 1443300100018 Xenon. The stopping detectors were 450 mm2 silicon 1443300100019 detectors (500 microm depth) capable of stopping 1443300100020 alpha-particles up to 33 MeV. 1443300100021 (IOCH) Multi-element ionization chamber containing 1443300100022 steel foils coated with films of U-235 and U-238 served1443300100023 as beam monitor. 1443300100024 METHOD (TOF) Determination of neutron energies was performed 1443300100025 via TOF measurements between microbursts (~250 ps 1443300100026 wide with a 1.8 microsec interval) of the LAMPF 800 1443300100027 MeV primary proton beam on the spallation target and 1443300100028 hits in our detectors. 1443300100029 CORRECTION Background was subtracted using data from empty target 1443300100030 runs in precisely the same configuration as the 1443300100031 56Fe-target runs. 1443300100032 HISTORY (20150805C) BP 1443300100033 ENDBIB 31 0 1443300100034 NOCOMMON 0 0 1443300100035 ENDSUBENT 34 0 1443300199999 SUBENT 14433002 20150805 14091443300200001 BIB 3 4 1443300200002 REACTION (26-FE-56(N,X)2-HE-4,,SIG) 1443300200003 ERR-ANALYS (DATA-ERR) All sources of errors included. 1443300200004 STATUS (TABLE) page 317. 1443300200005 (DEP,14433003) 1443300200006 ENDBIB 4 0 1443300200007 NOCOMMON 0 0 1443300200008 DATA 4 1 1443300200009 EN-MIN EN-MAX DATA DATA-ERR 1443300200010 MEV MEV MB MB 1443300200011 13.5 14.5 41.2 3.5 1443300200012 ENDDATA 3 0 1443300200013 ENDSUBENT 12 0 1443300299999 SUBENT 14433003 20150805 14091443300300001 BIB 3 3 1443300300002 REACTION (26-FE-56(N,X)2-HE-4,,SIG) 1443300300003 ERR-ANALYS (ERR-S) Error bars are purely statistical. 1443300300004 STATUS (CURVE) Fig. 2, page 316. 1443300300005 ENDBIB 3 0 1443300300006 NOCOMMON 0 0 1443300300007 DATA 3 29 1443300300008 EN DATA ERR-S 1443300300009 MEV MB MB 1443300300010 4.287 0.435 1443300300011 4.743 0.714 1443300300012 6.778 6.525 1443300300013 7.324 9.704 1443300300014 7.780 11.916 1443300300015 8.297 12.885 1443300300016 8.813 16.479 1443300300017 9.329 17.863 0.967 1443300300018 9.845 21.870 1.105 1443300300019 10.331 22.287 1.243 1443300300020 10.847 25.743 1.381 1443300300021 11.363 29.750 1.657 1443300300022 11.880 31.687 1.519 1443300300023 12.396 33.485 1.381 1443300300024 12.882 35.144 1.934 1443300300025 13.367 40.119 2.210 1443300300026 13.884 39.431 2.072 1443300300027 14.400 43.439 2.072 1443300300028 14.887 41.093 2.348 1443300300029 15.585 45.930 2.071 1443300300030 16.648 48.974 1.934 1443300300031 17.590 52.155 2.071 1443300300032 18.592 58.099 2.348 1443300300033 19.594 63.905 2.624 1443300300034 21.112 72.890 1.795 1443300300035 23.148 75.938 2.210 1443300300036 25.123 80.506 2.487 1443300300037 27.069 80.515 2.762 1443300300038 29.042 90.469 2.900 1443300300039 ENDDATA 31 0 1443300300040 ENDSUBENT 39 0 1443300399999 SUBENT 14433004 20150805 14091443300400001 BIB 4 4 1443300400002 REACTION (26-FE-56(N,X)2-HE-4,,DE) 1443300400003 ANALYSIS (INTAD) 1443300400004 ERR-ANALYS (ERR-S) Error bars are purely statistical. 1443300400005 STATUS (CURVE) Fig. 3, page 316. 1443300400006 ENDBIB 4 0 1443300400007 COMMON 1 3 1443300400008 EN 1443300400009 MEV 1443300400010 14.0 1443300400011 ENDCOMMON 3 0 1443300400012 DATA 3 10 1443300400013 E DATA ERR-S 1443300400014 MEV MB/MEV MB/MEV 1443300400015 3.498 0.586 0.343 1443300400016 4.527 1.593 0.466 1443300400017 5.535 1.375 0.539 1443300400018 6.538 3.656 0.466 1443300400019 7.563 7.164 0.613 1443300400020 8.569 7.852 0.564 1443300400021 9.529 7.020 0.490 1443300400022 10.564 5.282 0.637 1443300400023 11.550 3.617 0.343 1443300400024 12.511 2.589 0.270 1443300400025 ENDDATA 12 0 1443300400026 ENDSUBENT 25 0 1443300499999 SUBENT 14433005 20150805 14091443300500001 BIB 5 6 1443300500002 REACTION (26-FE-56(N,X)2-HE-4,,DA) 1443300500003 DETECTOR Angular acceptance of detectors ranged between 1443300500004 +-9 and 13 degrees. 1443300500005 ANALYSIS (INTED) 1443300500006 ERR-ANALYS (ERR-S) Error bars are purely statistical. 1443300500007 STATUS (CURVE) Fig. 4, page 316. 1443300500008 ENDBIB 6 0 1443300500009 COMMON 1 3 1443300500010 EN 1443300500011 MEV 1443300500012 14.0 1443300500013 ENDCOMMON 3 0 1443300500014 DATA 3 4 1443300500015 ANG DATA ERR-S 1443300500016 ADEG MB/SR MB/SR 1443300500017 30. 5.219 0.351 1443300500018 60. 3.563 0.140 1443300500019 90. 2.785 0.421 1443300500020 135. 2.284 0.246 1443300500021 ENDDATA 6 0 1443300500022 ENDSUBENT 21 0 1443300599999 ENDENTRY 5 0 1443399999999
