11. One cannot foretell whether or not the Soviets would
attend our demonstration firing.
It would appear that their most
advantageous position, if they desire to keep their country's
tests closed to observers, would be as follows:
attend our shcet,
they should not
criticizing it as a propaganda stunt;
they should
claim that their own firings are "clean" and hence the U. S. is
just putting on a show;
they could have certain other members of
the Soviet Bloc attend to secure all possible information;
they
should claim again that their only interest is in stopping all
tests.
CONCLUS ION
|This probably cota be accomplished without
revealing to the Soviets important design information not already
known to them.
However,
it would be necessary to declassify for
the purpose the total yield and total fission yield of the shot.
To determine the fission yield at all convincingly,
the radio-
chemical analysis of samples should be the method used.
