Gram L024900100014 amounts of the purified target materials in small L024900100015 cylindrical glass vials fitted with polyethylene L024900100016 stoppers were irradiated. L024900100017 METHOD (ACTIV) Irradiated for 1-12 hr periods. L024900100018 (GSPEC) Gross fission-product gamma-ray spectra were L024900100019 recorded at 4, 6, 9, 18, 30, 45, 68, 80 and 96 hr, and L024900100020 10-150 days after the end of the irradiation. L024900100021 (CHSEP) L024900100022 DETECTOR (GELI) Ge(Li) detector (10 cm3) with energy resolution L024900100023 of 2.55 keV FWHM at the 1.33248-MeV Co-60 line. L024900100024 The detector had a peak-to-Compton ratio of 17 to 1. L024900100025 MONITOR 237U, produced by the 238U(G,N)237Ureaction, was taken L024900100026 as an internal standard to correlate the gamma-ray L024900100027 spectra taken at different intervals and also to enableL024900100028 calculations of the relative yields of nuclides from L024900100029 the spectra. L024900100030 DECAY-DATA Nuclear data of the nuclides analyzed by gross L024900100031 fission-product gamma-ray spectrometry (GSPEC) and L024900100032 analyzed after radiochemical separations from 238U L024900100033 fission(CHSEP) were taken by authors from different L024900100034 references (see table 1 and 2 in the text).
