C253600100008 INSTITUTE (1USABRK,1USAUCX) C253600100009 FACILITY (SYNCH,1USABRK) Bevelac. C253600100010 INC-SPECT 2.5x10*10 particles/min. C253600100011 SAMPLE The target array for this experiment consisted of 3 C253600100012 foils of natural uranium separated from each other by C253600100013 150 mm. The foils, varying in thickness from 33 to 72 C253600100014 mg/cm2 and surrounded by ~15 mg/cm2 Al catcher foils. C253600100015 METHOD (CHSEP,GSPEC) Foils were irradiated for 162 min at C253600100016 the BEVALAC. Gamma and X-ray spectroscopic C253600100017 measurements of the radioactivity induced in the C253600100018 target and catcher foils began one hour after C253600100019 bombardment and continued for about three weeks. Over C253600100020 76 radionuclides were identified in this work on the C253600100021 basis of their gamma-, X-ray energy, half-life and C253600100022 radiation intensity. C253600100023 CORRECTION Based upon the variation of activity with foil C253600100024 thickness, corrections (of ~10-30%) were made to each C253600100025 measured activity to account for the effects C253600100026 of:secondary-induced reactions. The corrections were C253600100027 roughly independent of A with maximum corrections C253600100028 being applied to the neutron-rich fission product C253600100029 activities. Recoil losses from the target were C253600100030 measured to be negligibly small. C253600100031 ERR-ANALYS (DATA-ERR) No details on sources of uncertainties.
