Breit, Tube, and Dahl did do these tests but later (3 yrs later) admitted
there were some serious flaws in their measuring techniques. They did
other tests using x-rays as the potential determination method but some of
this data was classified as the results were used in early atomic
experiments with regard to weapons development at Los Alamos.
