SAMPLE Samples were placed within collimator, 250 cm from 2310500100030
target in 0-deg direction. 2310500100031
METHOD (TOF) For neutron spectrum measurement. 2310500100032
(ACTIV) Samples were irradiated two times: 2310500100033
1 hour to measure short half-life radionuclides, 2310500100034
10 hours - long. 2310500100035
DETECTOR (SCIN) 14-cm-diameter, 10-cm-long NE213 liquid 2310500100036
scintillation detector, placed at 11 m from Li target 2310500100037
in forward direction at 0-deg. 2310500100038
(HPGE) To measure gammas from sample after irradiation 2310500100039
several times. 2310500100040
ANALYSIS Activation reaction rates were estimated by the peak 2310500100041
counts of gamma-ray spectra, the peak efficiency of 2310500100042
HPGe detector (calculated by EGS4 code). 2310500100043
Ratio of peak reaction rate from Emin to Emax and the 2310500100044
total reaction rate from Eth to Emax - peak-to total 2310500100045
ratio of reaction rate - was estimated using measured 2310500100046
neutron flux and cross-section data of ENDF/B-VI. 2310500100047
CORRECTION For self-absorption of gamma-rays in samples, 2310500100048
for the coincidence-summing effect, 2310500100049
for beam current fluctuation during irradiation, 2310500100050
for contribution of low-energy tail neutrons. 2310500100051
