The work on collective electronic oscillations in the silicone liquid Dow Corning 705 was revised. Newly analyzed data on electron bombardment gave better agreement with results of analyzed vuv optical reflectance values for energy loss than earlier results indicated. As previously reported, electron and photon mean free paths and absolute photoyields were calculated from reanalyzed liquid water data in the 2 to 25 eV region. These electron mean free paths were calculated from formamide electron mean free paths scaled for valence electron density. The formamide mean free paths were derived using Born approximation by Ashley and Williams. An alternate approach to calculation of electron mean free path in organic and inorganic matter proposed by Seah and Dench has been followed. A paper detailing the water data and discrepancies in electron mean free path is in preparation. A survey of a range of liquids with request to reflectivity and photoemission was completed. Absorbance measurements in the 25,000 to 2700 A region were made on a number of the insulating liquids. As a result, a series of n-ethylene glycols with particularly high dipole moments was chosen for study. The main thrust of the current contract period has been a study of these liquids which include ethylene glycol, diethylene glycol, triethylene glycol and tetraethylene glycol.
