The multiple scattering of fast electrons by thin foils has been calculated on the assumption that the electrons are diffracted by minute crystals forming the foil. The method used was that of Williams and the resulting distribution of the projected angles is given. The result shows a better agreement with most of the experiments than the previous theories.

A detailed theoretical treatment is given in order to study the anomalies of the small angle reflection of cathode rays from a cleavage face of rocksalt. It is shown that the correction formula of the positions of the reflection spectra by previous authors cannot be applied to the lowest order reflection. There are, moreover, serious discrepancies between the theoretically obtained feature of the lowest order reflection and that obtained experimentally.

The causes of the anomalies in the low order reflection of the cathode rays from the surface of a single crystal have been considered. It is shown that the anomalies cannot be attributed to the effect of the azimuth nor the poorness of the approximation of the calculation, but can be explained, for the greater part, by a simple geometrical consideration.

Total probabilities for the beta decay and the orbital electron capture are calculated according to the Fermi theory in the case of the first and the second forbidden transitions. In this case, the ratio cf the probabilities for the positron emission to those for the K-electron capture are also estimated as a function of the nuclear charge and the nuclear radius.
