Aluminum catcher foils of 0.025 mm 3300300100020 thickness were placed on the target. 3300300100021 For radiochemical method 30 microgm target nuclide was 3300300100022 evaporated on 0.025 mm thick superpure aluminum foil. 3300300100023 For analyses using mass spectrometry, 0.5 to 1 mg of 3300300100024 target nuclide was evaporated in thin walled quartz 3300300100025 ampoule. Each sealed ampoule was wrapped in superpure 3300300100026 aluminum foil. 3300300100027 DETECTOR (GELI) For the gamma spectrometric measurements, the 3300300100028 catcher foils were mounted and counted in a fixed 3300300100029 geometry of Ge(Li)detector coupled to a multichannel 3300300100030 analyser. 3300300100031 (PROPC) The radiochemical measurement was followed on 3300300100032 an end window gas flow beta proportional counter. 3300300100033 (MAGSP) Mass spectrometric isotope measurements were 3300300100034 done using CH-5 and MAT-261 thermal ionization 3300300100035 mass spectrometer. 3300300100036 METHOD (ACTIV) The targets for mass spectrometric method were 3300300100037 irradiated for 15, 30, and 90 days. 3300300100038 For the gamma spectrometric and the radiochemical 3300300100039 methods were irradiated for a period of 10 t0 24 hrs. 3300300100040 (GSPEC) For the gamma spectrometric measurements the 3300300100041 catcher foils were mounted and counted in a fixed 3300300100042 geometry on a Ge(Li) detector coupled to a multichannel3300300100043 analyser. The system had a resolution of 2.2 keV 3300300100044 at 660 keV. The fission product activity was followed 3300300100045 for its decay. The photopeak area was obtained by 3300300100046 subtraction of linear component from the sum of channel3300300100047 contents defining the peak. 3300300100048 (CHSEP) The radiochemical separations of the fission 3300300100049 products 89,91-Sr, 97-Zr, 99-Mo, 111,112,113-Ag, 3300300100050 115-Cd, 121-Sn, 123-Sn, 125-Sn, 127-Sb and 140-Ba were 3300300100051 carried out using standard radiochemical procedures and3300300100052 measurement of their activities were carried out using 3300300100053 end window gas flow beta proportional counter. 3300300100054 (ASEP) For mass spectrometric determinations the 3300300100055 sample in quartz ampoule was dissolved after a cooling 3300300100056 period of 2 months to 1 year. Isotopic ratios were 3300300100057 determined using CH-5 and MAT-261 thermal ionization 3300300100058 mass spectrometers after chemical treatment. 3300300100059 Preferential evaporation and ionization technique was 3300300100060 used for sequential determination of isotopic ratios of3300300100061 Rb, Cs, Ba, Sr, Ce, Eu, Nd and Zr from the same 3300300100062 filament loading. Mo and Ru isotope ratios were 3300300100063 determined after purification from Zr as well as other 3300300100064 fission products. 3300300100065 INC-SPECT Thermal neutron spectra 3300300100066 ERR-ANALYS (DATA-ERR) The estimated uncertainties on the fission 3300300100067 yield values determined using the mass spectrometric 3300300100068 method are 1-3%. 3300300100069 The estimated uncertainties on the fission yield values3300300100070 in asymmetric region are 4% and about 12% for symmetric3300300100071 region for gamma spectrometric region and the 3300300100072 radiochemical methods. 3300300100073 STATUS (TABLE) Table 1-4 of Radiochim.Acta,42(1987)169 3300300100074 (APRVD) Approved by Dr. S.A.Chitabar (2007-08-16) 3300300100075 HISTORY (20070807C) Compiled by Nirupama N.
