On the Reflection Spectrum of Cathode Rays from Natural Faces of Pyrite.

Abstract

The mean inner potential of pyrite was obtained by the analysis of the reflection spectra of cathode rays from natural faces of the crystal using some samples. The apparent refractive indices obtained from each order reflection show decrease at low order reflections. The value obtained for the mean inner potential and the intensity distributions in each order reflection spot which is observed asymmetrically with respect to intensity maximum, show variations with the samples. A possible interpretation for these phenomena is described.
