    Notes: The effect of 3.5 keV electron irradiation on adhesion and contact resistivity of the Ag/YBa2Cu3O7 interface has been studied using an evaporated silver layer on c-axis oriented superconducting YBa2Cu3O7 thin films. Electron doses ranged between 1016 and 1018 electrons/cm2. The Q-tip method of adhesion testing showed that even at the lowest electron dose adhesion is significantly improved. The contact resistivity of the interface was measured using a cross-junction four-point probe. Contact resistivity was unchanged at the lowest electron dose but increased as the electron dose increased. A theoretical model involving an electron irradiation damaged layer at the interface has been developed to explain measured contact resistivity changes. © 1995 American Institute of Physics.

    Description / Table of Contents: Zusammenfassung Mit Hilfe der VESCF-MO-Methode wird dasp-σ-Bindungsmodell der Halogen-Halogen-Bindung untersucht. Verschiedene Verfahren für die Abschätzung des Kernresonanzintegralsβ werden diskutiert. Legt man ein semi-empirisches Verfahren für die Abschätzung dieses Integrals zugrunde, so zeigt sich, daß das Modell die Gleichgewichtsbindungsabstände in Halogen-Halogen-Molekülen in guter Übereinstimmung mit dem experimentellen Befund wiedergibt. Für die Wellen-funktionen der Moleküle erhält man dagegen keine besonders genaue Beschreibung. Die implizierten Annahmen dieser semi-empirischen Näherung werden im Detail geprüft.
    Abstract: Résumé La méthode VESCF MO est utilisée pour étudier le modèle de liaisonp-σ pour la liaison halogène-halogène. Des procédés pour estimer les valeurs de l'intégrale de résonance de coeurβ sont discutés. On trouve que si cette intégrale est évaluée par un procédé semi-empirique, le modèle prédit correctement les longueurs de liaison pour les molécules halogènes-halogène, mais ne fournit pas une description précise de la fonction d'onde moléculaire. Les hypothèses implicites dans l'approche semiempirique sont examinées an détail.
    Notes: Abstract The VESCF-MO method is used to investigate thep-σ bonding model of halogen-halogen bonding. Procedures for estimating values of the core resonance integral,β, are discussed. It is found that if a semi-empirical procedure is used for estimating this integral, the model adequately predicts equilibrium bond-lengths for halogen-halogen molecules, but does not give an accurate description of the molecular wavefunction. The implicit assumptions of the semi-empirical approach are examined in some detail.
