Abstract:A re-analysis of the diffuse far UV radiation (lambdalambda 1350–1480 Å) observed in the sky region ofl IIap180° and 0°lapb IIlap40° is presented, as a revised version of a paper by Hayakawaet al. (1969). In comparison with the previous one, the value of the half optical depth of the Galazxy tau in our wavelength region is reduced, and the values of the albedo coefficient lambda and the forward phase functiong are not well determined. If, however, we combine our results with the theoretical model of interstellar grains by Gilra, the value of tau is given by 0.13(5)laptaulap0.18(5).
