and analysis details. 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

SAMPLE .The samples of mass-separated isotopes and samples 2242800100042
of natural abundance were used. Powder samples were 2242800100043

between two aluminium foils 10*10 mm 0.2 mm thick. 2242800100045
Samples' weights are between 38 and 100 milligram 2242800100046
