preinitiation test shot was called for; if there was anything really
strange involved, e.g, in the neutron distribution, it could best be
studied in the laboratory.
Experiments might be done at Pajarito,
Referring to the curve of yield versus initiation time, as established
by the three available points and the existing theory, he said it
seemed extremely improbable that the curve should have a ink or
shoulder which would make invalid the present smooth extrapolation

would be of questionable value.
Dr. Rabi said these arguments would make him perfectly happy if
there existed a good theory for the yleld.
However, he would like to
see another point on the curve closer to zero time, in order to check
the validity of the extrapolation.

Dr. Mark said that the difficulties in predicting yields béfore
the shots were not now relevant.
The yields of all of the shots made ~-
40 to 50 in number, and in assorted configurations, etc. -- can now he
calculated well,
There is every evidence that the calculations are
sound, and no reason to think there is anything mysterious or interesting in the untested region of the yield curve.
