摘要:

AbstractEs wird gezeigt, daß diese beiden Methoden sich in einfacher Weise kombinieren lassen, wenn man den optimalen Skalenfaktor λ so bestimmt, daß die Summe der Wurzeln der Konfigurationswechselwirkungs‐Rechnung ein Minimum wird. Dies wird durch einige Testrechnungen mit Gauss‐Orbitalen für die ersten vier Zustände des H‐Atoms

摘要:

AbstractA simple theoretical model for the dependence of electrolytic conductance on the concentration of neutral molecules is proposed.We show that the main contribution to the constant of friction is due to hard collisions between ions and neutral molecules. The theory is compared with experimental data for ionic mobilities in several aqueous solutions of nonelectrolytes and with conductance data for pure electrolytes at various pressures.The agreement between theoretical and experimental data is satisfactory.

摘要:

The molecular distribution functions of classical systems of particles with long‐range and short‐range interactions are calculated. The BBGKY‐Hierarchy is solved by means of a perturbation development which in the case of merely short‐range interaction, is identical with the usual density expansion. Binary distribution functions, osmotic pressure and free excess energy are presented explicitly and di

摘要:

AbstractFür die 4p2P‐)Terme im KupferI‐Spektrum wird ein Störansatz gemacht, der eine Konfigurationsmischung mit deny2P‐ undz2P‐Termen beinhaltet. Es gelingt, aus der Störung derA‐Faktoren der 4p2P‐Terme Störkoeffizienten zu errechnen, die sich an der Störung der Spin‐Bahn‐Aufspaltung bestätigen lassen.Schließlich wird gezeigt, daß die Störung auf den bisher nicht gemessenenB‐Faktor des 4p2P3/2‐Terms keinen

摘要:

AbstractThe mean residence time τiof alkali ions on both atomically clean and strongly gas‐covered surfaces of polycrystalline wolfram has been studied with a recently developed technique of combining modulated atomic and/or molecular beams from vapors of alkali metals and alkali halides with phase‐sensitive mass‐spectrometic detection. The experimental arrangement allows the direct determination of the mean residence time τiof an ion on a metal surface under extremely clean surface conditions and at very small incident beam intensities (109− 1012particles cm.−2sec.−1) to avoid an influence of surface coverage by the beam material itself. In addition, it allows mass‐spectrometric determination of the effect of the composition of the incident beam on τi. The dependence of τion the surface temperatureTis given by Frenkel's equation τi= τ 0iexp (Ei/kT), whereEiis the ion desorption energy. With alkali chloride sources, the values tabulated below were determined over ranges within the temperature region 1100 °K

AbstractWith the coefficients of a Taylor expansion of the correlation functionC(\documentclass{article}\pagestyle{empty}\begin{document}$ \overrightarrow \xi $\end{document}, τ) up to the second order in\documentclass{article}\pagestyle{empty}\begin{document}$ \overrightarrow \xi $\end{document}, τ three (or four) velocities can be defined to describe the space‐time behaviour in a satisfying manner. They have a simple geometrical relationship among each other. The necessary measurements for the computation of these coefficients are discus
