C247500100009 SAMPLE (82-PB-207,ENR=0.924) Targets of enriched 207Pb (92.4 C247500100010 percent) in their foil form. C247500100011 METHOD (CHSEP) Targets were bombarded by the 65 MeV helium C247500100012 ions in Berkeley, California. The targets were then C247500100013 flown to the laboratories in Bellingham where the C247500100014 fission fragments were separated by standard C247500100015 radiochemical techniques. The period of time between C247500100016 the end of bombardment to the time when counting of C247500100017 the radiochemically separated species began, was C247500100018 about l0 h.
