    Description / Table of Contents: Riassunto Lo spettro di assorbimento ottico di atomi di Li isolati in matrice di Ar, Kr e Xe è analizzato mediante un metodo pseudopotenziale. Per i sistemi Li/Ar e Li/Kr si conclude che il sito matriciale stabile per l'atomo metallico è formato du un gruppo di quatro vacanze disposte in modo tetraedrico. Per il sistema Li/Xe vari siti d'intrappolamento di diversa stabilità sono possibili. I risultati sono in buon accordo con i dati sperimentali ed è cosí possibile riconoscere una tendenza generale nel modo d'isolamento degli atomi metallici.
    Abstract: Резюме С помощью псевдопотециального метода анализируегся спектр оптического поглощения атома Li, расположенного в матрице Ar, Kr и Xe. Для систем Li/Ar и Li/Kr мы заключаем, что устойчивая конфигурация ловушки для атома металла представляет кластер из четырех вакансий расположенных в виде тетраздра. Полученные результаты хорошо согласуются с экспериментами и позволяют понять обшую тенденцию обособленного поведения атомов металла.
    Notes: Summary The optical-absorption spectrum of the Li atom isolated in Ar, Kr and Xe matrices is analysed by a pseudopotential method. For the systems Li/Ar and Li/Kr we concluded that the stable trapping site is a cluster of 4 tetrahedrally arranged vacancies. For Li/Xe several trapping sites of different stability are possible. The results agree very well with the experiments and it is possible to recognize a general trend in the isolation behaviour of the metal atoms.

    Description / Table of Contents: Riassunto Per mezzo di un metodo a pseudopotenziale si calcola la perturbazione da matrici di gas raro sui livelli elettronici esternis ep di atomi di Mg e Ca. Uno spostamento verso il «blu» delle linee di assorbimento della giusta grandezza è stato calcolato per Mg e Ca in matrice di Ar e Kr. Per questi sistemi si conclude che il sito d’isolamento stabile è costituito da un assieme di quattro vacanze disposte in maniera tetraedrica. Si può cosí riconoscere un andamento generale per il comportamento in isolamento degli atomi metallici.
    Notes: Summary By a pseudopotential method the perturbation of the outer electronicss andp levels of Mg and Ca by rare-gas matrices is calculated. A blue-shift for theP←S absorption lines of the right magnitude is calculated for Mg and Ca in Ar and Kr matrices. For these systems we conclude that the stable trapping site is a cluster of 4 tetrahedrally arranged vacancies. Related to these findings it is possible to recognize a general trend in the isolation behaviour of the metal atoms.

    The density and polarization of an ion-dipole-electrolyte near a charged wall (1995)

    Notes: The structure of the hard sphere dipolar liquid and the electrolyte with added hard sphere ions near a charged hard planar electrode has been investigated with the reference hypernetted chain integral equation (RHNC). We find a decrease of the dielectric function ε near the wall, a decrease of ε in the fluid due to saturation, a field dependent change in the dipole density near the wall, and a decrease of the ion density near the electrode due to solvation. Related to the demixing instability of the ion-dipole mixture, the ions suddenly concentrate near the surface at higher fields and lead to a sharp increase in the differential capacitance. Also electrostriction in the pure dipolar liquid with a field in the bulk is considered. © 1995 American Institute of Physics.

    The structure of water at a planar wall: An integral equation approach with the central force model (1994)

    Notes: The structure of liquid water in contact with a planar wall is calculated for the central force model by which water is modeled as a stoichiometric mixture of partially charged hydrogen and oxygen atoms interacting via effective spherical pair potentials. The density profiles near the wall are obtained from the Wertheim–Lovett–Mou–Buff equation extended to mixtures with coulombic interactions. The correlations in the bulk liquid are calculated by adding bridge functions of appropriate reference hard sphere systems to the hypernetted chain equation. We have obtained structural (stoichiometry, hydrogen bonds) and thermodynamic properties in good agreement with computer simulations. We also expose the water to electric fields due to a surface charge on the wall.

    A local HNC/HNC approximation for the 2:2-RPM electrolytes at a charged wall (1986)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: A local HNC/HNC approximation is proposed and applied to 2:2 electrolytes near a charged hard wall. The results are compared with Monte Carlo data and other theories such as HNC/HNC, HNC/MSA, BGY, and MPB5. A remarkable improvement of the density profiles and of the diffuse layer potential is obtained. We show that the HNC closure for the ion–ion correlations, when used in the local scheme, always gives better results than those obtained from the MSA closure. The necessary algorithm for solving the local HNC/HNC equations is also presented.
