    Description / Table of Contents: ESR Studies of Radiation Processes in Phosphate GlassesRadiation processes in phosphate glasses are investigated by ESR and optical measurements. ESR shows a hole-centre in the systems K2O/P2O5 and K2O/MGO/P2O5 which depends on manner and concentration of the cations. Its nature is explained in somewhat a different way than given by BEEKENKAMP or by MIURA and HASEGAWA. Another hole-centre which is independent of cations is discussed in agreement with optical investigations. The electrons set free by radiation react with O2 solved in the glass or with cations. The particels Ag0, Ag2+, Ag+2 have been found and Agn+4 may be present too in the system K2O/MgO/Ag2O/P2O5. The system K2O/MgO/Tl2O/P2O5 shows analogous reactions, but full explanation of the lines could not yet be given.
    Notes: Durch ESR-Untersuchungen und Vergleiche mit optischen Messungen werden Aussagen über die durch Bestrahlung in Phosphatgläsern ablaufenden Vorgänge gemacht. In den Systemen K2O/P2O5 und K2O/MgO/P2O5 wird durch ESR-Messungen ein kationenabhängiges Lochzentrum gefunden, dessen Natur in Abweichung von den Modellen nach BEEKENKAMP und nach MIURA u. HASEGAWA erklärt wird. Ein weiteres kationenunabhängiges Lochzentrum wird in Übereinstimmung mit optischen Untersuchungen gedeutet. Die durch Bestrahlung freigesetzten Elektronen lagern sich an im Glas gelösten Sauerstoff (O2) an oder reagieren mit den Kationen. Im System K2O/MgO/Ag2O/P2O5 werden die Teilchen Ag0, Ag2+, Ag+2 gefunden und Agn+4 wahrscheinlich gemacht. Für das System K2O/MgO/Tl2O/P2O5 gelten analoge Verhältnisse. Eine ausführliche Zuordnung konnte aber dabei noch nicht vorgenommen werden.

    Description: Three types of aerosol were detected from observations of the Martian sky, Phobos, and the sun with the Viking imaging cameras. Atmospheric optical depths were derived from observations of the objects' brightness. Data on the absorption coefficient, mean size, and shape of aerosols were obtained from studies of the sky brightness, using a multiple-scattering computer code. The aerosol types were water ice ground fog, a higher-level ice cloud (polar hood), and soil particles suspended at heights up to 30 km. The properties of each type of aerosol are discussed. The data are subjected to thorough analysis, and the results are summarized.
