Presented before the American Nuclear Society Meeting in San Francisco, California, December 14, 1960. A discussion is given of the objectives of the program established to develop methods for measuring and predicting infinite medium neutron spectra. Primary emphasis was placed on studies of moderation in water, with secondary emphasis in graphite, beryllium oxide, zirconium hydride, and polyethylene. Typical infinite medium results are shown for the hydrogen atom in cadmium sulfate solutions. Two geometries for stab-lattice spectra measurements are illustrated. The axial flux distribution of 1.4-ev neutrons in a 4-in.-thick tank of water poisoned to 6 barns per H atom is given. The results are shown graphically for the calculation of the spectrum at the peak in the flux distribution using diffusion theory. Leakage spectra are included for 4-in.- thick boric acid and water slabs, separately. (B.O.G.)
