    Description / Table of Contents: Zusammenfassung Die Polarisierbarkeit der Atome und der positiven und negativen Ionen von He bis Kr ist nach einem verhältnismäßig einfachen Verfahren mit Hartree-Fock-Funktionen berechnet worden. Die Ergebnisse stimmen recht gut mit schon vorhandenen theoretischen und experimentellen Ergebnissen überein.
    Abstract: Résumé On a calculé les polarisabilités dipolaires pour tous les ions positifs, les atomes neutres et les ions négatifs jusqu'au Krypton en employant des fonctions analytiques de Hartree-Fock. L'accord avec autres résultats théoriques et les valeurs expérimentales est satisfaissant. La simple méthode employée ici offre donc une alternative en comparison avec des méthodes plus élaborées.
    Notes: Abstract The electric dipole polarizabilities have been evaluated from Hartree-Fock functions for the positive ions, neutral atoms, and negative ions from He to Kr. The agreement with previous theoretical results and with experimental values, whenever available, is rather satisfactory. On the basis of this agreement, the simple method used appears to be competitive with more elaborate treatments.

    Notes: Abstract Two types of approximate functions have been tested through the evaluation of various physical properties: for ground states, double-ζ, SCF functions have been used, while for excited states the calculations have been carried out using the expectation values obtained from the Hartree-Fock functions for the corresponding lowest configuration. The agreement with the Hartree-Fock values or the experimental results, respectively, can be considered to be very satisfactory.

    Notes: Abstract The promotion energies, ionization potentials, electron affinities, and orbital electronegativities for the valence states of importance in atoms of the first two rows of the periodic system have been evaluated from analytical Hartree-Fock functions for the corresponding groundstates. The agreement with existing values, determined from experimental data, is very satisfactory.
