The curve was obtained by 3150000100025 irradiating a set of samples with different reaction3150000100026 threshold energies. 3150000100027 - In the 13 to 20 MeV energy 3150000100028 region, the effect of low-energy neutrons was 3150000100029 deducted by irradiating an empty target that was 3150000100030 free of T. 3150000100031 Neutron spectra for the D(d,n)He-3 and T(d,n)He-4 3150000100032 reactions at the 0-degree angle have been measured 3150000100033 by the time-of-flying method for the deuteron beams 3150000100034 of 2 and 3 MeV. 3150000100035 DETECTOR (GELI) 3150000100036 PART-DET (DG) 3150000100037 STATUS (TABLE) Data from table 4 of Nuclear Science and 3150000100038 Engineering No.131, 267-274 (1999) 3150000100039 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 3150000100040 Have to be confirm by authors: e-mail 23.06.99 3150000100041 DECAY-DATA (27-CO-58-G,70.916D,DG,811.,0.9945) 3150000100042 Have to be confirm by authors: e-mail 23.06.99 3150000100043 HISTORY (19990621C) VZ 3150000100044 (20090604U) SD: cosmetic corrections were made 3150000100045 ENDBIB 43 0 3150000100046 NOCOMMON 0 0 3150000100047 ENDSUBENT 46 0 3150000199999 SUBENT 31500002 20090605 31383150000200001 BIB 1 1 3150000200002 REACTION (30-ZN-64(N,P)29-CU-64,,SIG) 3150000200003 ENDBIB 1 0 3150000200004 NOCOMMON 0 0 3150000200005 DATA 4 13 3150000200006 EN EN-RSL DATA ERR-T 3150000200007 MEV MEV MB MB 3150000200008 4.00 0.16 132.9 3.8 3150000200009 4.90 0.10 181.6 6.3 3150000200010 6.00 0.13 205.2 7.9 3150000200011 7.00 0.15 219.5 8.4 3150000200012 8.37 0.58 235. 12. 3150000200013 9.37 0.46 251. 14. 3150000200014 9.5 0.5 257. 13. 3150000200015 9.9 0.5 249. 13. 3150000200016 10.40 0.33 249. 13. 3150000200017 11.40 0.35 243. 12. 3150000200018 14.65 0.20 134. 4. 3150000200019 17.99 0.15 61. 8. 3150000200020 19.02 0.22 57. 5. 3150000200021 ENDDATA 15 0 3150000200022 ENDSUBENT 21 0 3150000299999 SUBENT 31500003 20090605 31383150000300001 BIB 1 1 3150000300002 REACTION (28-NI-58(N,P)27-CO-58,,SIG) 3150000300003 ENDBIB 1 0 3150000300004 NOCOMMON 0 0 3150000300005 DATA 4 7 3150000300006 EN EN-RSL DATA ERR-T 3150000300007 MEV MEV MB MB 3150000300008 4.00 0.16 352.4 5.6 3150000300009 4.90 0.10 481.1 7.5 3150000300010 6.00 0.13 581.1 14.0 3150000300011 7.00 0.15 628.6 15.9 3150000300012 14.00 0.05 329. 9. 3150000300013 17.99 0.15 101. 11. 3150000300014 19.02 0.22 89.8 5.4 3150000300015 ENDDATA 9 0 3150000300016 ENDSUBENT 15 0 3150000399999 ENDENTRY 3 0 3150099999999
