On the Inner Potentials of Graphite and Molybdenite.

抄録

Precise values of mean inner potential of graphite and molybdenite were determined by analysing cathode ray reflection spectra. They were found to be 13.0 volts for graphite and 19.5 volts for molybdenite. The apparent decrease of inner potential in low order reflections, which was first observed by Yamaguti, was studied experimentally in detail and compared with the theoretical values calculated by Bethe's theory.
