The effect of paramagnetic impurities on superconductors with energy-gap anisotropy is studied using the Shiba-Rusinov theory and treating the ordinary and exchange interactions equally. The Abrikosov-Gor'kov-theory results are a special case of our calculations. The transition temperature Tc and the jump in specific heat at Tc are calculated. The emphasis is to clarify the roles of the ordinary and the exchange interactions in the electron-impurity scattering. The difference between the results of the Shiba-Rusinov and Abrikosov-Gor'kov theories is brought out.

An accurate intermolecular potential of the HFD‐C form is proposed which appears to be the best representation of the Ar–Kr interaction. The potential, which possesses the correct long range behavior, predicts a wide variety of macroscopic and microscopic data. It is consistent with accurate second virial, viscosity, and diffusion coefficients. Differential scattering and low as well as high energy total cross section data are accurately predicted.

Literature intermolecular potentials for the Ar–Xe and Kr–Xesystems are analyzed and critically assessed as to their abilities to predict dilute gas bulk and microscopic properties. Two new potentials of the HFD‐C form (HFDAX1 and HFDKX1) are proposed for the Ar–Xe and Kr–Xe interactions, respectively, which accurately predict a large number of properties.
Thermodynamic behavior in the critical region of the spin van der Waals model is considered when the number of spins in the system is large but finite (1?N? 1 / 3), where ε=(T?T c )/T c , T c being the critical t...

Thermodynamic behavior in the critical region of the spin van der Waals model is considered when the number of spins in the system is large but finite (1?N<∞). The specific heat curve is shown to possess a steep, yet smooth, maximum which turns into a singularity as the number of spins becomes infinite. In the case of the finite system, this maximum occurs at ε=ε*=O(N ?1/3), where ε=(T?T c )/T c , T c being the critical temperature of the infinite system.

A theoretical analysis based on the method of system-size expansion of the master equation is carried out for a generalized nonlinear stochastic model with cubic interactions. The resulting Fokker-Planck equation enables us to derive the relevant probability distributions in the critical region as well as away from it; in the former case, the distribution turns out to be non-Gaussian and is dominated by fluctuations which are non-negligible. The onset of a first-order phase transition in the system is investigated in some detail. In particular, a Maxwell-type "theorem of equal areas" is discovered which might hold for a much wider class of systems with cubic interactions.
The detection of Auger electrons under MeV ion bombardment has been investigated as a surface analytical probe of particular utility for low- and middle-Z elements. Using UHV chambers at Bell Laboratories and Chalk Ri...

The use of N ( E ) = N FE k (∂ E ( k )/∂ k ) −1 as the electronic density of states for disordered metallic systems is critically examined. The present examination shows that its use is reasonable and that the applicability of the nearly-free-electron theory to the binary alloys of simple metals becomes worse and worse in going from the case of small charge transfer to the case of large charge transfer. Der Gebrauch des Ausdruckes N ( E ) = N FE k (∂ E ( k )/∂ k ) −1 für die Elektronenzustandsdichte der fehlgeordneten metallischen Systeme wird kritisch untersucht. Die gegenwärtige Untersuchung zeigt, daß der Ausdruck vernünftige Resultate bietet. Die Applizierbarkeit der Theorie der beinahe freien Elektronen auf binäre Legierungen der einfachen Metalle wird immer schlechter, wenn man von dem Falle kleinen Ladungstransfers zum Fall großen Ladungstransfers geht.

We demonstrate the size of a correction to the nearly-free-electron approximation required to yield the right packing densities. The influence of this correction on the electronic density of states below the Fermi surface and on the interionic potentials is examined.

It is demonstrated that the perturbative correction, appearing in the structure factor of the simple liquid metals in the one-component-plasma model, is important and may have to be calculated more rigorously than by the usual semi-non-local or local pseudopotential theory.
