Each sample was wrapped in 3284600100014 0.1 mm thick aluminium foils, sandwiched between two 3284600100015 monitor gold foils (purity > 99.99%) with thickness 3284600100016 0.1 mm, and then wrapped in 0.3 mm thick cadmium 3284600100017 foils. 3284600100018 DETECTOR (LONGC) To monitor neutron flux. 3284600100019 (HPGE) The gamma-ray activities of 76As and 98Au were 3284600100020 determined. 3284600100021 METHOD (ACTIV) The samples were irradiated simultaneously at 3284600100022 0, 30, 60, 90 and 120 deg with respect to the 3284600100023 incident beam. The irradiation lasted 27 h and 17.5 h 3284600100024 by the neutrons were produced by Li-7(p,n) and T(p,n) 3284600100025 reaction, respectively. 3284600100026 CORRECTION Corrections have been made for neutron multiple 3284600100027 scattering and attenuation of neutron fluence rate. 3284600100028 EN EN-ERR DATA-EXP DATA-EXP-ERR CORRECTION 3284600100029 KEV KEV MB MB NO-DIM 3284600100030 29. 7. 284.0 19. 1.055 3284600100031 59. 16. 209.0 14. 1.015 3284600100032 121. 27. 123.8 8.9 1.017 3284600100033 196. 30. 114.2 7.7 0.980 3284600100034 215. 44. 107.3 7.2 1.012 3284600100035 230. 12. 98.5 6.6 0.989 3284600100036 376. 87. 52.9 3.8 0.935 3284600100037 655. 134. 27.6 2.1 1.031 3284600100038 962. 135. 20.4 1.6 0.989 3284600100039 1100. 83. 16.8 1.4 0.991 3284600100040 MONITOR (79-AU-197(N,G)79-AU-198,,SIG) 3284600100041 DECAY-MON (79-AU-198-G,2.6935D,DG,411.8,0.955) 3284600100042 MONIT-REF (,,3,ENDF/B-VI,7925,2001) 3284600100043 ERR-ANALYS (ERR-T,6.7,7.8) Total uncertainty, 6.7-7.8% 3284600100044 (ERR-S,1.,2.)
