The angle between the d+ beam and 2321600100020 the axis of the collimated neutron beam was 80 degree, 2321600100021 which resulted in a 14.2 MeV neutron energy. 2321600100022 The distance between an exit of the collimator and the 2321600100023 sample was 15 cm. 2321600100024 INC-SPECT The typical value of neutron fluence at the sample 2321600100025 position was 6.5E+5 n/cm**2/s. 2321600100026 DETECTOR (HPGE) 36% HPGe detector - to measure induced activity.2321600100027 The distance between the sample and the HPGe detector 2321600100028 surface was 5 cm. 2321600100029 SAMPLE Samples were 1 mm thick rectangular (10 mm x 20 mm) or 2321600100030 disk-shape (15 mm diameter). 2321600100031 Nuclei Chemical form Weight,mg Abundance 2321600100032 Al-27,natural Al 949.6 Al-27 100% 2321600100033 Sm-144,enriched Sm(2)O(3) 45.01 Sm-144 96.47%2321600100034 Pb-206,enriched Pb 138.0 Pb-206 99.56%2321600100035 Pb-208,enriched Pb 123.1 Pb-208 99.86%2321600100036 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 2321600100037 The typical neutron fluence rates at the irradiation 2321600100038 positions were measured by Al27(n,a)Na24 reaction. 2321600100039 See H.Maekawa,Y.Ikeda,Y.Oyama,S.Yamaguchi,T.Nakamura; 2321600100040 JAERI-M 83-219. 2321600100041 METHOD (GSPEC) 2321600100042 CORRECTION The effect of the scattered neutron from the sample, 2321600100043 the sample folder and the atmosphere was taken into 2321600100044 account - calculated by the MCNP-4C: 2321600100045 the neutron fluence rate at the HPGe detector surface 2321600100046 was 4.0E-4 times against the sample position. 2321600100047 ERR-ANALYS (ERR-S,3.,50.)
