INC-SPECT An average particle intensity of 7.8x10**13 C254600200004
protons/min. 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. C254600200028
