    Notes: Abstract Investigations of the low temperature electrical resistance of the alkali metals, taking into account the actual spectrum of the lattice waves and the actual form of the wave functions to the best degree of approximation possible, are reported. It was found that for Na and K, where the approximation of free electrons is allowed, the umklapp processes augmented the temperature dependent electrical resistance only by few percents. In the case of Li, umklapp processes are more important, because of the fact that the wave functions differ from plane waves considerably. But in the whole temperature region the magnitude of the electrical resistance is determined by normal processes. Deviations from Matthiessen's rule caused by point defects are studied. In spite of the different refinements, the theory is not able to explain the experimental results in a satisfactory manner.

    Notes: Es wird die magnetische Suszeptibilität des kristallisierten Arsens gemessen. Der in der Literatur angegebene Wert (χAtom = -23.10-6) gilt nicht für kristallisiertes, sondern für amorphes Arsen. Das rhomboedrische Arsen besitzt vielmehr χAtom-Werte von -5,5 ± 1.10-6 bei Zimmertemperatur und + 1 ± 1,5 ·10-6 bei - 183°.
