C254600200005 SAMPLE A natural uranium foil of thickness 33.5 mg/cm2 C254600200006 surrounded by mylar catcher foils of thickness 35.5 C254600200007 mg/cm2. C254600200008 DETECTOR (GELI) C254600200009 METHOD (ACTIV,CHSEP) A natural uranium foil was irradiated C254600200010 for 63 min in an external beam of 28 GeV protons from C254600200011 the Alternating Gradient Synchrotron at Brookhaven C254600200012 National Laboratory. The intensity of the beam C254600200013 striking the target was determined by measuring the C254600200014 yields of 22Na and 24Na in a 12.72 mg/cm2 Al foil C254600200015 irradiated simultaneously with the U foil. Following C254600200016 a one day delay for shipment of the irradiated foils C254600200017 to the Lawrence Berkeley Laboratory, analysis of the C254600200018 radioactivities of the target fragments began. The C254600200019 irradiated U foil and the mylar catcher foils were C254600200020 cut approximately in half; the target was counted C254600200021 before and after the cutting process, allowing an C254600200022 exact determination of the relative fractions. one C254600200023 half of the target and its associated mylar catcher C254600200024 foils were subjected to direct gamma-ray spectroscopy, C254600200025 while a chemical group separation procedure was C254600200026 applied to the other 33.5 mg/cm2 U foil half without C254600200027 its catcher foils.
