D609900100014 (RCHEM,REC) After the irradiation, the aluminium D609900100015 catcher foil for each uranium foil facing the beam D609900100016 was dissolved. D609900100017 Tellurium and iodine were separated radiochemically D609900100018 from the dissolved solution within 5-15 min from the D609900100019 end of the irradiation. D609900100020 (GSPEC) Standard aliquots of purified tellurium and D609900100021 iodine samples were counted for optimum durations as D609900100022 a function of time at a fixed geometry on an energy D609900100023 and efficiency calibrated 90 cc HPGe detector D609900100024 coupled to a 4 K multichannel analyser in live time D609900100025 mode. D609900100026 Counting was carried out over a period of three half- D609900100027 lives to confirm the purity of the individual D609900100028 photopeak of the concerned radionuclide. D609900100029 DETECTOR (HPGE) The resolution of the detector system was 2.0 D609900100030 keV at 1332.0 keV and the dead time during the D609900100031 counting was always less than 10% to avoid the pile- D609900100032 up effect. D609900100033 MISC-COL (MISC) fission fragment angular momenta (Jrms) D609900100034 CORRECTION Photopeaks were corrected for the Compton background. D609900100035 ERR-ANALYS (DATA-ERR) Including the errors due to D609900100036 - counting statistics D609900100037 - absolute abundances of the gamma lines D609900100038 - detector efficiencies D609900100039 (as well as those associated with the cumulative D609900100040 yield of the precursor.)
