TEMPERATURE OF REGOLITH IN COLD TRAPS ON THE MOON A.A. Berezhnoi Sternberg Astronomical Institute Moscow, Russia The hypothesis of the existence of the lunar ice in cold traps was stated in (Watson et al., ... Arnold, 1979) estimated the mean temperature on the surface of lunar cold traps as 40-90 K. We plotted the dependence of regolith mean temperature on depth for these two values of mean temperature on the surface (see figure 1). ... Arnold J.R. Ice in the lunar polar regions, J.

... Optical properties of oxide dust grains. ... Optical constants: . ... The deternimation of the optical constants was made from measured reflectance at near normal incidence of the polished sample surfaces (0.2 - 500 micron) with following Lorentz oscillator fit (typically 5 oscilators) from ultraviolet to mid-infrared and Kramers-Kronig analysis in the region of the infrared vibrational bands. The oxides Fe x Mg 1-x O for x = 1.0, 0.9, 0.8, 0.7, 0.5, and 0.4 were considered in the paper. ...
