The maximum 2187800100010 intensity occurs at a neutron energy of about 22.5MeV 2187800100011 and the FWHM of the spectrum is 15.8 MeV. Neutron flux2187800100012 densities were calculated from the integrated charge 2187800100013 at the Be converter using Faraday cup. 2187800100014 The neutron flux densities available at irradiation 2187800100015 geometry were about 8.E+10 neutrons/cm**2/sec. 2187800100016 Neutron spectrum provided by S.M.Qaim ( 29-12-2016): 2187800100017 units: energy - MeV, yield - 10**8n/(muC*MeV*sr) 2187800100018 Energy Neutron yield Energy Neutron yield 2187800100019 12.5 124. 29.5 140. 2187800100020 13.5 158. 30.5 115. 2187800100021 14.5 175. 31.5 102. 2187800100022 15.5 199. 32.5 85. 2187800100023 16.5 196. 33.5 76. 2187800100024 17.5 208. 34.5 58. 2187800100025 18.5 232. 35.5 56. 2187800100026 19.5 251. 36.5 47. 2187800100027 20.5 260. 37.5 46. 2187800100028 22.5 259. 38.5 40. 2187800100029 23.5 246. 39.5 34. 2187800100030 24.5 238. 40.5 31. 2187800100031 25.5 219. 41.5 27. 2187800100032 26.5 192. 42.5 24. 2187800100033 27.5 172. 43.5 21. 2187800100034 28.5 152. 2187800100035 REL-REF (R,O1924002,G.W.Schweimer,J,NP/A,100,537,1967) 2187800100036 Ref. for neutron spectrum 2187800100037 (N,,S.M.Qaim+,J,JIN,36,3639,1974) Reference for 2187800100038 usual corrections applied (only list of references 2187800100039 is given in J,JIN,36,3639 - 1,2,9-11 ) 2187800100040 (N,,H.J.Probst+,J,ARI,27,431,1976) Reference for 2187800100041 sources of errors . 2187800100042 (O,A0181001,S.M.Sahakundu+,J,ARI,30,3,1979) 2187800100043 Al-27(A,N)P-30, P-31(P,X)P-30 data. 2187800100044 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) As a flux monitor. 2187800100045 SAMPLE The sample material, PCl5 or S, was sealed under 2187800100046 vacuum in polyethylene tubes and monitor aluminum 2187800100047 wrapped around it. 2187800100048 METHOD (ACTIV) Activation 2187800100049 (GSPEC) 2187800100050 DETECTOR (GELI) 2187800100051 ANALYSIS (DECAY) Annihilation radiation from decay of P-30 as 2187800100052 well as radiation from the monitor foil was counted on 2187800100053 Ge(Li) detector and gamma-ray spectra analyzed on a 2187800100054 4096 channel analyzer.
