water, air and soil between 30 and 2310500100004 70 MeV. 2310500100005 AUTHOR (H.Yashima, K.Terunuma, T.Nakamura, M.Hagiwara, 2310500100006 N.Kawata, M.Baba) 2310500100007 INSTITUTE (2JPNTOH)

30,35,40,50,60,70 MeV bombarded 2310500100012 natural Li target. 5 % energy loss in target. 2310500100013 1-m-long tapered iron and concrete collimator. 2310500100014 INC-SPECT Neutron energy spectrum was measured using TOF method 2310500100015 by liquid scintillation detector. 2310500100016 Obtained neutron spectra are given on Fig.2 of 2310500100017 J,NSTS,4,70,200403. 2310500100018

2310500100031 METHOD (TOF) For neutron spectrum measurement. 2310500100032 (ACTIV) Samples were irradiated two times: 2310500100033 1 hour to measure short half-life radionuclides, 2310500100034 10 hours - long. 2310500100035 DETECTOR (SCIN) 14-cm-diameter, 10-cm-long NE213 liquid 2310500100036 scintillation detector, placed at 11 m from Li target 2310500100037 in forward direction at 0-deg. 2310500100038 (HPGE) To measure gammas from sample after irradiation 2310500100039 several times. 2310500100040 ANALYSIS Activation reaction rates were estimated by the peak 2310500100041 counts of gamma-ray spectra, the peak efficiency of 2310500100042 HPGe detector (calculated by EGS4 code). 2310500100043 Ratio of peak reaction rate from Emin to Emax and the 2310500100044 total reaction rate from Eth to Emax - peak-to total 2310500100045 ratio of reaction rate - was estimated using measured 2310500100046 neutron flux and cross-section data of ENDF/B-VI. 2310500100047 CORRECTION For self-absorption of gamma-rays in samples, 2310500100048 for the coincidence-summing effect, 2310500100049 for beam current fluctuation during irradiation, 2310500100050 for contribution of low-energy tail neutrons. 2310500100051 ADD-RES (COMP) PHITS calculations. 2310500100052 ERR-ANALYS (ERR-T) Total error. 2310500100053 The following error components are included: 2310500100054 (ERR-S,,10.)
