Pulse generation frequency was 3224200100017 equal to 7.25 MHz, average neutron intensity 10E7/s in 3224200100018 4PI. 3224200100019 SAMPLE Investigated samples of nat Sn and nat C with masses 3224200100020 mSn=3208 g, mC=1600 g were irradiated by neutrons. 3224200100021 DETECTOR (NAICR) The emitted prompt gamma-rays are traversed 3224200100022 the flight path and detected by the NaI(Tl) 3224200100023 scintillator cylindrical detector of sizes: diameter 3224200100024 150 mm, height 100 mm. The flight path equals 1.76 m 3224200100025 to ensure reliable separation of prompt gamma-rays from3224200100026 neutron and gamma-ray background. For reducing 3224200100027 influence of cosmic rays, the NaI(Tl) detector was 3224200100028 surrounded by Geiger counters working in 3224200100029 anti-coincidence mode with spectrometer signals. 3224200100030 METHOD (TOF) Time-of-flight method was employed to separate 3224200100031 prompt gamma-rays signals from the whole time spectrum.3224200100032 ADD-RES (COMP) The experimental results were compared with 3224200100033 theoretical calculations performed using EMPIRE 3.2 3224200100034 and TALYS 1.6 codes. 3224200100035 ERR-ANALYS (ERR-S)Uncertainties of the cross section were 3224200100036 estimated in assumption that the amplitude spectrum is 3224200100037 followed by Gauss distributions due to the large number3224200100038 of external independent factors. 3224200100039 STATUS (TABLE) Data were received from B.M.Bondar 20171002. 3224200100040 HISTORY (20171002C) UKRNDC 3224200100041 (20171002R) 3224200100042 ENDBIB 40 0 3224200100043 COMMON 2 3 3224200100044 EN EN-RSL 3224200100045 MEV MEV 3224200100046 14.1 0.2 3224200100047 ENDCOMMON 3 0 3224200100048 ENDSUBENT 47 0 3224200199999 SUBENT 32242002 20171002 31813224200200001 BIB 1 1 3224200200002 REACTION (50-SN-0(N,X)0-G-0,,DA/DE,,4PI) 3224200200003 ENDBIB 1 0 3224200200004 COMMON 1 3 3224200200005 ANG 3224200200006 ADEG 3224200200007 90. 3224200200008 ENDCOMMON 3 0 3224200200009 DATA 3 32 3224200200010 E DATA ERR-S 3224200200011 MEV MB/MEV MB/MEV 3224200200012 1.94 605.677 90.851 3224200200013 2.32 612.109 91.816 3224200200014 2.65 433.192 64.978 3224200200015 3.01 337.940 50.691 3224200200016 3.42 197.227 29.584 3224200200017 3.91 140.031 21.004 3224200200018 4.29 139.378 20.906 3224200200019 4.87 100.068 40.027 3224200200020 5.33 25.452 10.181 3224200200021 5.80 18.274 7.309 3224200200022 6.13 10.274 0.941 3224200200023 6.57 8.302 0.495 3224200200024 7.03 6.468 0.370 3224200200025 7.58 4.641 0.246 3224200200026 8.02 3.226 1.129 3224200200027 8.51 1.815 0.635 3224200200028 8.87 0.911 0.319 3224200200029 9.33 0.330 0.115 3224200200030 9.80 0.226 0.079 3224200200031 10.40 0.195 0.045 3224200200032 11.06 0.179 0.054 3224200200033 11.71 0.164 0.059 3224200200034 12.31 0.155 0.066 3224200200035 12.89 0.160 0.080 3224200200036 13.41 0.142 0.075 3224200200037 14.04 0.146 0.085 3224200200038 14.61 0.130 0.068 3224200200039 15.11 0.113 0.067 3224200200040 15.63 0.109 0.086 3224200200041 16.20 0.123 0.096 3224200200042 16.72 0.100 0.078 3224200200043 17.32 0.103 0.081 3224200200044 ENDDATA 34 0 3224200200045 ENDSUBENT 44 0 3224200299999 SUBENT 32242003 20171002 31813224200300001 BIB 2 5 3224200300002 REACTION (6-C-0(N,X)0-G-0,PAR,SIG) 3224200300003 COMMENT Observation of gamma-transitions for natC was been able3224200300004 only from the first excited level with Eg=4.43 MeV due3224200300005 to low intensities of gamma-transitions with other 3224200300006 energies. 3224200300007 ENDBIB 5 0 3224200300008 COMMON 1 3 3224200300009 E 3224200300010 MEV 3224200300011 4.43 3224200300012 ENDCOMMON 3 0 3224200300013 DATA 2 1 3224200300014 DATA ERR-S 3224200300015 MB MB 3224200300016 232. 30. 3224200300017 ENDDATA 3 0 3224200300018 ENDSUBENT 17 0 3224200399999 ENDENTRY 3 0 3224299999999
