Energy of Cohesion, Compressibility, and the Potential Energy Functions of the Graphite System

L. A. Girifalco、Robert A. Lad1956-10-01OpenAlex

The lattice summations of the potential energy of importance in the graphite system have been computed by direct summation assuming a Lennard-Jones 6–12 potential between carbon atoms. From these summations, potential energy curves were constructed for interactions between a carbon atom and a graphite monolayer, betwe…

Electron Characteristic Energy Losses in Metals and Compounds

Lewis B. Leder1956-09-15Physical Review

The characteristic energy loss spectra of electrons in the metals Al, C, Sb, Ca, Pb, Na, and Te and compounds of these metals have been measured with an improved measuring technique designed to give more reliable intensity relationships, and it is found that, with the exception of ${\mathrm{Al}}_{2}$${\mathrm{O}}_{3}$…

Nature of Edge Emission in Cadmium Sulfide

John Lambe、Clifford C. Klick、D. L. Dexter1956-09-15Physical Review

Experimental and theoretical evidence is reviewed to determine if edge emission in CdS is due to exciton recombination or is characteristic of a center. New evidence is presented which shows that edge luminescence may be produced in CdS at low temperatures by stimulating with infrared light, and simultaneous measureme…

Triple Hysteresis Loops and the Free-Energy Function in the Vicinity of the 5°C Transition in BaTiO3

E. J. Huibregtse、Donald R. Young1956-09-15Physical Review

The effect of an electric field on the transition between the orthorhombic and tetragonal states in single crystals of BaTi${\mathrm{O}}_{3}$ has been investigated. With zero bias the tetragonal to orthorhombic transition occurs near 5\ifmmode^\circ\else\textdegree\fi{}C and the inverse transition at 11\ifmmode^\circ\…

Coulomb Scattering of Relativistic Electrons by Point Nuclei

Noah Sherman1956-09-15Physical Review

The Mott series for the Coulomb scattering of electrons by point nuclei have been evaluated numerically with the aid of the UNIVAC computer. Calculations of the series for $F(\ensuremath{\theta})$ and $G(\ensuremath{\theta})$, the scattering cross section, and the polarization asymmetry factor, $S(\ensuremath{\theta})…

Bremsstrahlung and Pair Production in Condensed Media at High Energies

A.B. Migdal1956-09-15OpenAlex

The effect of multiple scattering on bremsstrahlung and pair production is considered. The probability of these processes decreases considerably at energies \ensuremath{\gtrsim}${10}^{13}$ ev.The calculations are carried out with the aid of the density matrix. The formulas thus obtained yield the probability of pair p…
