Errors' structure is given 2242800100011 METHOD (ACTIV) Activation 2242800100012 FACILITY (CCW,2JPNOSA) The intense 14 MeV neutron source 2242800100013 OKTAVIAN at Osaka University. 2242800100014 INC-SOURCE (D-T) The D-beam energy was 300 keV and the intensity 2242800100015 was 5 milliamps. A sample transport system of six 2242800100016 pneumatic tubes provided irradiation positions giving 2242800100017 monochromatic neutrons of 13.4-14.9 MeV. Another tube 2242800100018 was put at -105 deg to check the symmetry of the sys- 2242800100019 tem. The irradiation positions was about 15 cm from 2242800100020 the tritium target. An additional tube set at -22.5 2242800100021 deg and at 1.5 cm distance was used when strong acti- 2242800100022 vities were required. The transfer time was about 2242800100023 2 sec. 2242800100024 INC-SPECT Neutron energies cover range from 14.9 to 13.4 MeV 2242800100025 angles of irradiation are 0, 50, 75, 105, 125, 155 2242800100026 adeg. Distance between tritium target and sample is 2242800100027 15 cm. The effective energy of incident neutrons at 2242800100028 irradiation position was determined by the ratio of 2242800100029 90-Zr(n,2n) and 93-Nb(n,2n)92m-Nb cross section 2242800100030 DETECTOR (HPGE ) Two Ge detectors with efficiencies of 12 and 2242800100031 16%, having resolution of 1.75 and 2.00 keV, 2242800100032 respectively, were used to measure the induced acti- 2242800100033 vities. Each detector was covered with 5 mm acrylic 2242800100034 absorber to reduce beta-rays. The efficiency calibra- 2242800100035 tion was performed at a distance of 5 cm using 24-Na, 2242800100036 56-Co, 133-Ba, 152-Eu and 154-Eu sources. 2242800100037 MONITOR (13-AL-27(N,A)11-NA-24,,SIG) 2242800100038 (13-AL-27(N,P)12-MG-27,,SIG) 2242800100039 DECAY-MON (11-NA-24,14.959HR,DG,1368.6,0.99994) 2242800100040 (12-MG-27,9.46MIN,DG,843.8,.720) 2242800100041 SAMPLE .The samples of mass-separated isotopes and samples 2242800100042 of natural abundance were used.
