Warum interferieren die Wahrscheinlichkeiten?

The wavelike interference law connecting various transition probabilities, usually taken as the expression of a basic and irreducible quantum dualism, is derived as a consequence of the postulate that a general connection law between the probabilities exists at all, together with requirements of symmetry, invariance, and other features of a non-wavelike nature. Duality is thus divested of its fundamental character, and a way is found to understand quantum mechanics on a non-quantal basis.     

Über die Energie-Impuls-Objekte des Gravitationsfeldes

From translational invariance we have essentially two possibilities for energymomentum-objects of gravitation: the pseudotensor found byEinstein and an object similar to that ofMøller. We must prefer the latter not only because its more reasonable properties, but also from a more axiomatic point of view. A difference of our work from that ofMøller and another (“purely canonical”) formulation of the conservation theorem are pointed out. .     

Über die Photoleitung von Anthrazen

The dependence of the photocurrent on voltage, light intensity and electrode separation and also the decay-time of the photocurrent is measured. All these measurements are largely influenced by the electrode material. The results obtained with Cu I- and Al-electrodes and also with insulating electrodes are given and the different behavior is discussed by means of a model. Hereby conclusions are made about the mean ranges and the mobility of the holes which are mainly responsible for the photocurrent.

Über die Wechselwirkung zweier Heliumatome

The interaction energy between two helium atoms in the ground state is calculated by a variational principle. Besides the valence energy 387·exp(?4,42R) (R in Å, energy in eV) and the van der Waals energy ?0,58/R ^5,9 an additional energy term 366·exp(?7,15R) is obtained which is particularly important forR?3 Å. A potential minimum but no equilibrium exists because the zero point energy is too large. The results of other authors are discussed and compared.     

Mikrophy'sikalische Vorgänge,die die Entstehung der Schnellen Schichtungswellen in der Neonglimmentladung bedingen

Zusammenfassung Im nachstehenden Artikel werden mikrophysikalische Vorgänge behandelt, die das Auftreten schneller Schichtungswellen in Neonglimmentladungen veranlassen können. Es werden sowohl die qualitativen Abhängigkeiten, als auch die ziffernmäigen Werte der Parameter der Schichtungswellen mit den charakteristischen Gröenwerten der in diesem Entladungstypus vor sich gehenden Vorgänge verglichen. Auf Grund der vorgenommenen Vergleiche kann gesagt werden, da die Relaxationszeiten der schnellen Wellen durch die Diffusionslebensdauer der atomaren, bzw. molekularen Ionen gegeben sind.
