between 30 and 23105 1 4 70 MeV. 23105 1 5 AUTHOR (H.Yashima, K.Terunuma, T.Nakamura, M.Hagiwara, 23105 1 6 N.Kawata, M.Baba) 23105 1 7 INSTITUTE (2JPNTOH) 23105 1 8 REFERENCE (J,NSTS,4,70,2004) 23105 1 9 FACILITY (ISOCY,2JPNTOH) AVF Cyclotron of the Cyclotron and 23105 1 10 Radioisotope Center. 23105 1 11 INC-SOURCE (P-LI7) Protons of 30,35,40,50,60,70 MeV bombarded 23105 1 12 natural Li target. 5 % energy loss in target. 23105 1 13 1-m-long tapered iron and concrete collimator. 23105 1 14 INC-SPECT Neutron energy spectrum was measured using TOF method 23105 1 15 by liquid scintillation detector. 23105 1 16 Obtained neutron spectra are given on Fig.2 of 23105 1 17 J,NSTS,4,70,200403. 23105 1 18 Characteristics of neutron fields: 23105 1 19 Proton Li-target Peak Peak Percentage 23105

250 cm from 23105 1 30 target in 0-deg direction. 23105 1 31 METHOD (TOF) For neutron spectrum measurement. 23105 1 32 (ACTIV) Samples were irradiated two times: 23105 1 33 1 hour to measure short half-life radionuclides, 23105 1 34 10 hours - long. 23105 1 35 DETECTOR (SCIN) 14-cm-diameter, 10-cm-long NE213 liquid 23105 1 36 scintillation detector, placed at 11 m from Li target 23105 1 37 in forward direction at 0-deg. 23105 1 38 (HPGE) To measure gammas from sample after irradiation 23105 1 39 several times. 23105 1 40 ANALYSIS Activation reaction rates were estimated by the peak 23105 1 41 counts of gamma-ray spectra, the peak efficiency of 23105 1 42 HPGe detector (calculated by EGS4 code). 23105 1 43 Ratio of peak reaction rate from Emin to Emax and the 23105 1 44 total reaction rate from Eth to Emax - peak-to total 23105 1 45 ratio of reaction rate - was estimated using measured 23105 1 46 neutron flux and cross-section data of ENDF/B-VI. 23105 1 47 CORRECTION For self-absorption of gamma-rays in samples, 23105 1 48 for the coincidence-summing effect, 23105 1 49 for beam current fluctuation during irradiation, 23105 1 50 for contribution of low-energy tail neutrons. 23105 1 51 ADD-RES (COMP) PHITS calculations. 23105 1 52 ERR-ANALYS (ERR-T) Total error. 23105 1 53 The following error components are included: 23105 1 54 (ERR-S,,10.) statistical error,
