The resonance frequencies of a system containing two or four magnetic sublattices with different gyro-magnetic ratios are calculated. It is found that in many cases the results reduce to the standard formulas of ferromagnetic and antiferromagnetic resonance; they are stated, however, in terms of an effective gyromagne…
A general method is given, by which problems of elastic plane strain in a bimetallic medium can be reduced to standard problems of potential theory. A bimetallic medium is one where the elastic constants are different on either side of a plane. The boundary between the two semi-infinite solids can be either a complete…

It is shown that the unusual observed saturation behavior of the microwave electron spin resonance associated with $F$ centers in KCl, NaCl, and KBr crystals can be accounted for if the overall width is ascribed to interaction between the $F$-center electrons and the nuclear magnetic moments of the ions adjacent to th…

The scintillation process has been studied in a number of systems involving a solid solution of an organic fluor in polystyrene or polyvinyltoluene. It has been determined that direct excitation of the solute by the ionizing radiation contributes a negligible amount to the observed scintillation for the concentrations…
Phase transitions in ceramic PbHf${\mathrm{O}}_{3}$ have been studied by dielectric and structural measurements. The dielectric constant is about 90 at room temperature, and its temperature dependence shows a small anomaly at 163\ifmmode^\circ\else\textdegree\fi{}C and a pronounced peak of 540 at 215\ifmmode^\circ\els…
A method for the calculation of the energy levels of an atom in terms of the experimentally observed energy levels of ions of higher ionization is developed. This method can be applied to a system of nonequivalent electrons, as well as equivalent electrons. The notion of fractional parentage is extended to systems of…
Measurements have been made of the electrical resistivity and Hall coefficient of semiconducting rutile both in the form of ceramics and single crystals from -190\ifmmode^\circ\else\textdegree\fi{}C to +500\ifmmode^\circ\else\textdegree\fi{}C. The samples were reduced in pure hydrogen for various times and temperature…
