Abstract:
Long spacings and physical properties are shown for a number of metallic salts of n-aliphatic acids. Among the salts are those of thallium, copper, lead, zinc, uranyl radical, iron, cobalt, nickel, magnesium, and the more soap-like members such as sodium, potassium, lithium and calcium. Spacings ranged from about 15 A to 40 A for the salts measured, which is of the correct size for use as a dispersing device in the X-ray spectral region 15 to 60 A. Some salts were found to have properties which negated their use as dispersing devices for X rays, while others were found to be potentially good analyzing crystals or three dimensional gratings. Of the compounds prepared, zinc, thallium and uranyl salts showed promise for use as dispersing devices for long wave X rays. Almost any desired long spacing may be ob tained with the right combination of metal and acid, and these spacings may be calculated once a group of three or more salts of a homologous series has been prepared. Results on some aro matic compounds such as monovalent metal salts of phthalic acid are discussed. These compounds show promise for use as single crystal analyzers for soft X rays. Soft X-ray spectra are shown using a layered barium stearate film on glass and potassium acid phthalate as analyzers.
