De, Schreiber said that the 3:2 relative value figure contained
an: assumption about the neutron velocity in U-233 which is somewhat
uncertain,
if Pajarito mcasurenents are correct the velocity may be |
higher than assumed, and the velative value correspondingly higher,
Dr. von Neumann put the argument for case B as: the bookkeeping
mainlyshows that case B would not make a major upset in the thermenuclear program; for all other purposes case B provides an important
degree of freedom.
