It was less than a generation ago that breakthroughs in nuclear physics led to the event which, on a midsummer morning in the New Mexico desert, ushered in the atomic age. The laboratory discoveries of the 1930s, the mobilization of scientific resour

Measurements of poor geometry scattering and back scattering are described for neutrons of energies of 0.2, 0.6, 1.5, and 3 Mev. The following materials were investigated: C, Be, ${\mathrm{B}}^{10}$, ${\mathrm{B}}^{11}$, BeO, Al, Fe, Cu, Co, Ni, Ta,

An artificial neutron source has been built which is very stable in operation and flexible in use. Using the D—D reaction, target currents of more than 200 microamperes at 300 kv give a neutron yield of 10 grams radium‐beryllium equivalent. It ha

A discussion of observations in magnetic resonance experiments and their relations to the processes involved involves consideration of the populations of magnetic states. By adding a population coordinate to an energy diagram a representation is obta

Apparatus is described by means of which a modulated source of slow neutrons is produced and their intensity determined as a function of time. The deuteron beam of a high voltage tube is deflected by a modulated electrostatic field in such a way as t

The backscattering of $d\ensuremath{-}d$ neutrons was investigated for several materials. A directional thick paraffin detector was used. The detector was sensitive primarily to neutrons which had been scattered elastically or with little energy loss

With the aid of neutron detectors having thresholds at 1, 5, and 12 Mev, the angular distributions and average cross sections of the C/sup 12/(He/sup 3/ ,n)O/sup 14/ reaction were investigated at 19-, 22-, and 25-Mev He/sup 3/ energy. All angular dis
