Abstract:

For the purpose of determining the dependency of the degree of polarization of lunar details on the wave length, a spectrographic survey of the lunar surface was performed near the quadratures by the author in June and July 1959 with a 220mm A3T-7 telescope, using three different positions of a polaroid mounted in front of the spectrographs slit. Angular positions of the polaroid were 0 deg, 60 deg and 120 deg. A total of 108 spectrograms of 12 lunar regions were taken, which included Plinius, Mare Tranquillitatis 3 regions, Palus Somni, Ray of Proclus, Oceanus Procellarum 3 regions, Copernicus, and ray aureoles of Copernicus and Kepler. Monochromatic values of polarization degree P sub lambda were calculated by V. G. Fesenkovs formula. An examination of the instrumental polarization, revealed an equality of 0.07 which was constant in the interval 390-620 millimicron. Author
