Graphs for 2040100100007 neutron spectra and data for average energies 2040100100008 (W,Liskien,197312) Numerical values. 2040100100009 SAMPLE Spontaneous fission of Cf-252 encapsulated 2040100100010 in a thin wall container giving 3.E+5 fission events 2040100100011 per minute 2040100100012 METHOD (TOF) Energy spectra were measured using nano- 2040100100013 second time-of-flight technique. 2040100100014 Neutron energy spectra of the spontaneous fission 2040100100015 process of 252Cf were measured in two experiments using2040100100016 the time-of-flight technique. 2040100100017 DETECTOR (SCIN) NE224 liquid scintillator, 5 cm diameter and 2040100100018 3.8 cm length for neutron detection. 2040100100019 .The relative efficiency of this detector was measured 2040100100020 in the energy region from 0.05 to 8.2 MeV relative to 2040100100021 the known angular distributions of the reactions: 2040100100022 T(p,n)3He, D(d,n)3He, 9Be(alpha,n)12C, H(n,el)H, 2040100100023 and 7Li(p,n)7Be at zero angle. 2040100100024 A second branch from 12.4 to 19.6 MeV was obtained 2040100100025 relative to the T(d,n)4He angular distribution. These 2040100100026 measurements were performed at the pulsed 3 MV Van de 2040100100027 Graaff accelerator of the CBNM. The different parts of 2040100100028 the efficiency curve were normalized to each other in 2040100100029 overlapping regions, while the gap could be easily 2040100100030 filled by extrapolating the two branches. 2040100100031 It is believed, that the relative efficiency of the 2040100100032 detector is known to about 2% below 2.5 MeV and above 2040100100033 this energy with increasing uncertainty 2040100100034 up to 5% at 19 MeV 2040100100035 The neutron detector was the same in both experiments,2040100100036 whereas the detector which gave the time signal when a 2040100100037 spontaneous fission event occurred, differed in the two2040100100038 experiments (see Subents 2,3). 2040100100039 REL-REF (I,,H.Liskien+,J,AND,11,569,1973) 2040100100040 (I,,H.Liskien+,J,NUK,8,315,1966) 2040100100041 (I,,J.B.Hunt+,C,72NEUHER,,935,1972) 2040100100042 -- Reactions for detector efficiency definition. 2040100100043 CORRECTION No correction was applied for delayed neutrons. 2040100100044 ERR-ANALYS .Errors, if present, given in proper SUBENTs. 2040100100045 .Energy uncertainty of each data point were derived 2040100100046 from the time uncertainty(+-1.5 ns). 2040100100047 HISTORY (19740705C) 2040100100048 (19750430E) 2040100100049 (20110707A) Date is corrected to 8 digit format, upper 2040100100050 case comments converted to lower case 2040100100051 (20110818U) Last checking has been done. 2040100100052 (20120707U) SD: Information from INC-SOURCE moved to 2040100100053 SAMPLE; FACILITY, MONITOR and MONIT-REF were deleted; 2040100100054 information moved to DETECTOR - it is used for detector2040100100055 efficiency definition. 2040100100056 ENDBIB 54 0 2040100100057 NOCOMMON 0 0 2040100100058 ENDSUBENT 57 0 2040100199999 SUBENT 20401002 20110818 22272040100200001 BIB 5 11 2040100200002 REACTION (98-CF-252(0,F)0-NN-1,PR,KE,,AV,DERIV) Averaged over 2040100200003 data in SUBENT 20401005 2040100200004 ANALYSIS .The combined result of the two maxwellian fits and 2040100200005 two direct averaging of data obtained by start of the 2040100200006 experiments by fission gamma rays and fission 2040100200007 fragments 2040100200008 ERR-ANALYS (ERR-S) Given in the initial compilation 2040100200009 STATUS (TABLE) From text of Atomkernenergie, vol.22, page 84, 2040100200010 (DEP,20401005) 2040100200011 HISTORY (20110818A) REACTION codes ",PR,AKE,N" changed to 2040100200012 "0-NN-1,PR,KE,,AV,DERIV". 2040100200013 ENDBIB 11 0 2040100200014 NOCOMMON 0 0 2040100200015 DATA 2 1 2040100200016 DATA ERR-S 2040100200017 MEV MEV 2040100200018 2.13 8.E-02 2040100200019 ENDDATA 3 0 2040100200020 ENDSUBENT 19 0 2040100299999 SUBENT 20401003 20110818 22272040100300001 BIB 8 17 2040100300002 REACTION (98-CF-252(0,F),PR,NU/DE,,REL) Reference quantity not 2040100300003 given 2040100300004 METHOD .Exp. 1.
