Neutron Scattering and Polarization by Ferromagnetic Materials
Neutron diffraction studies are reported on a series of magnetized and unmagnetized ferromagnetic materials. The diffraction patterns for unmagnetized, polycrystalline samples of Fe and Co are found to possess both nuclear and magnetic components with the latter in agreement with the magnetic scattering theory with re…

Measurement of Multiple Scattering of 15.7-Mev Electrons
The angular distribution of electrons scattered by thin Be and Au foils has been measured for angles where the multiple scattering is important. The $\frac{1}{e}$ widths of the distributions obtained with Au foils of 18.66 and 37.28 mg/${\mathrm{cm}}^{2}$ are 2.58\ifmmode^\circ\else\textdegree\fi{} and 3.76\ifmmode^\c…
A Note on the Propagation of Excitation in an Idealized Crystal
It is shown that, in insulators, overlapping of the electronic wave functions of near-by crystal constituents is not necessary for effective transfer of excitation energy by the "exciton" mechanism. The electromagnetic interaction of the "virtual" dipoles of the transition is sufficient to give rise to such transfer c…
