ANALYSIS   (DECAY) Nuclides were identified by chemical behavior, O064800100026

           (AREA) Total fission cross sections were obtained by   O064800100028 
           summing the mass distributions.                        O064800100029 
CORRECTION  Performed: Recoil loss of bismuth fission fragments,  O064800100030 
           never more Than 0.5%.                                  O064800100031

COMMENT    -By Authors- The incident energy values quoted here    O064800100034 
           are most probable values. The spread in energy is      O064800100035 
           about 10 MeV.                                          O064800100036 
           -By Compiler- A correction should have been performed  O064800100037 
           that takes into account a strong energy dependence of  O064800100038 
           The fission cross section.                             O064800100039 
           -By Compiler- The specified product of the absolute    O064800100040 
           monitor reaction could be formed also through          O064800100041 
           Cu-63(n,gamma) reaction due to low-energy neutron      O064800100042
