Letter to Doctor Wright Langham (Cont'd)
We ere also trying to calculate the absorption
of slow neutrons by steel. Do you know of any data at Los
Alemos which would help us out in this respect?
Unfortunately,
our experimental data from the pills placed around
the various ships is not too satisfactory because of the
tremendous scattering of the slow neutrons and the consequent difficulty in measuring the thickness of the steel
shielding.
Some tirie ago we wrote to Doctor Holloway
te see if any of the data obtained by Linenberger and Ogle
could be used to obtain neutron flux, but as yet have had
no reply.
I also wondered if you had succeeded in getting
Dessauer's neutron films calibrated.
The more data we can
collect the better chance we will have of coming out with
at least a reasonably accurate answer.
i hope this sudden onslaught wont completely
snow you under, but we are desperately trying to tie up
some of our loose ends before the powers that be make their
decisions.
Sincerely yours,
fete.
secant
Herbert Scoville, jr
