Original notebook housed in Box 42, Folder 3 of the Enrico Fermi Collection in the University of Chicago Library, Special Collections Research Center.
Summary: Notebook D14, "Numerical Calculations," November 12, 1943, to May 27, 1944, no index, 20 x 27 cm, consists almost entirely of numerical calculations, without, it would seem, much theory. Some of the calculations for the years 1941-1942 can be related to exponential experiments. The quality and format of this notebook are the same as Notebook D13 (Box 42, Folder 5). It may be that D13 is a continuation of this notebook.
