    Notes: Pseudopotentials are used for investigating the effects of relativity and correlation on atomic properties of Br and I, and on bond lengths and dissociation energies of the molecules HBr, HI, Br2, and I2. The pseudopotentials are adjusted to energies of Br6+ and I6+ on different levels of approximation: (i) to Hartree–Fock data for the nonrelativistic case, (ii) to Dirac–Fock data for the relativistic case, and (iii) to experimental energies for the relativistic case including correlation. At the highest level of approximation, atomic ionization energies, electron affinities, molecular dissociation energies, and bond lengths are obtained in good agreement with the experimental results.

    Description / Table of Contents: Zusammenfassung Die Albedo von Weizen- und Gerstenfeldern wurde in Derrimut, Victoria, Australien, in zwei aufeinanderfolgenden Vegetationszeiten gemessen. Eine dieser Vegetationszeiten (1966) war außerordentlich naß, die andere (1967) abnormal trocken. Die täglichen Albedowerte reichten von 0.13 bis 0.25 für Weizen und von 0.14 bis 0.36 für Gerste. Der Jahresgang der Albedo wird aus den Veränderungen in der Entwicklung der Pflanzen und im Bodenfeuchtegehalt erklärt. Die Änderung der Albedo in Abhängigkeit vom Höhenwinkel der Sonne wird ebenfalls diskutiert. Es werden auch die Unterschiede zwischen der Albedo bei klarem und bei bedecktem Himmel untersucht. Es zeigt sich, daß die Albedo an bedeckten Tagen der Albedo bei einem effektiven Sonnenwinkel von 45° gleichkommt.
    Notes: Summary The albedo of wheat and barley crops was measured during the course of two successive growing seasons, one of which was exceedingly wet (1966) and the other abnormally dry (1967) at Derrimut, Victoria, Australia. Daily albedo values ranged from 0.13 to 0.25 for wheat and from 0.14 to 0.36 for barley. The seasonal trends are explained in terms of changes in crop development and soil moisture. Albedo variation with solar elevation is also discussed. This leads to a consideration of the differences in albedo under clear and overcast skies, and it is shown that overcast days have an effective solar elevation of about 45°.
