Dielectric medium effects on loosely bound electrons

Joshua Jortner1962-05-01Molecular Physics

The problem of electron binding in solutions is treated on the basis of a continuum model. The polarizable medium is represented by a continuum, which can be characterized by macroscopic properties, e.g. the static and the optical dielectric constants. The motion of an additive electron is determined by its interactio…

Mullins Effect and Rubber-Filler Interaction

F. Bueche1962-05-01Rubber Chemistry and Technology

Abstract A previously-reported theory for the Mullins softening effect has been used to interpret various new data for the behavior of filled SBR, rubber under tensile load. The strength of the filler-rubber bond, the filler surface area per polymer molecule attachment, and the average filler surface separation have b…

Energy Levels of Er ii†

B. R. Judd、Louis C. Marquet1962-05-01Journal of the Optical Society of America

Eight low-lying levels of Er ii 4f12 6s have been observed to be grouped according to their energy in four close pairs. The centers of gravity of the pairs correspond to the energies of the four lowest levels of the core 4f12; the spacings between the two components of the pairs depend on the Coulomb interaction betwe…

Sound Waves in Water Containing Vapor Bubbles

G. T. Trammell1962-05-01Journal of Applied Physics

The rapid evaporation or condensation of a vapor bubble when out of equilibrium compared to the slow dissolving or growth of an air bubble results in quite different propagation properties of sound waves through water containing one or the other types of bubbles. Adapting a method developed by Foldy in his treatment o…

Determination of the Anisotropy in Thin Permalloy Films

W. D. Doyle1962-05-01Journal of Applied Physics

Four types of measurement on thin Permalloy films are discussed which in the coherent-rotation theory yield equivalent values for the anisotropy field Hk: (A) Hysteresis loop; (B) high field torque; (C) rotational hysteresis; (D) torque 90° to the easy axis. Results reported for several films show that the values obta…

Paramagnetic Resonance of TrivalentFe57in Zinc Oxide

W. M. Walsh、L. W. Rupp1962-05-01Physical Review

Tetrahedrally-coordinated trivalent iron has been found to be a common impurity in flux-grown crystals of zinc oxide. The room temperature paramagnetic resonance spectrum of isolated ions may be described by a conventional axial spin Hamiltonian with parameters: $g=2.0060\ifmmode\pm\else\textpm\fi{}0.0005$, $D=\ensure…

Some Observations on the Structure of Polytetrafluoroethylene

C. J. Speerschneider、Cheng-Dun Li1962-05-01Journal of Applied Physics

Changes in the structure of PTFE produced by different cooling rates from the sintering temperature and following permanent mechanical deformation have been studied with the electron microscope. Slow cooling rates resulted in longer and wider striated bands (which constitute the PTFE) than fast cooling rates, however,…

The effect of adding the rare-earth elements to cobalt, iron, and nickel has been investigated. Antiferromagnetic coupling was found to exist in the cobalt and iron rare-earth compounds. The moment per formula unit of the compound Co5Y is increased when Sm, Pr, and Nd are substituted for yttrium and decreased when Tm,…

Optical Absorption of Arsenic-Doped Degenerate Germanium

J. I. Pánkové、P Aigrain1962-05-01Physical Review

The infrared transmission of degenerate arsenic-doped germanium was measured at liquid-helium and at room temperature. The 4.2\ifmmode^\circ\else\textdegree\fi{}K data were used to calculate the energy gap of the degenerate material. For this, two operations were necessary: (1) to subtract the large effect of free car…
