Zur Theorie von Systemen aus drei Teilchen mit Coulomb-Wechselwirkung

The wave functions of muon molecules as well as of the corresponding electron molecules and of the systeme ⁺ e ^? e ⁺ have been approximated by simple analytical functions, the best choice of parameter values being obtained by straightforward variational procedure. The results are discussed in some detail and binding energies tabulated.     

Über den Einfluß der Coulomb-Wechselwirkung zwischen den Elektronen auf den Restwiderstand im Magnetfeld

Considering a gas of electrons, interacting viaCoulomb's law, containing randomly distributed, fixed impurities, it is shown that the calculation of the diagonal components of the static electrical conductivity tensor in an uniform magnetic field may be based on a quasi-particle-picture. The result holds at low temperatures in the first power of the density of impurities.     

Dauermagnetwerkstoffe mit bindern

If one knows the diagram of demagnetization of the magnet in plastic binder and knows the packing density, the curve of demagnetization of the used magnetic powder can be plotted. This procedure may also be inverted. Using anisotropic magnets with binders, a technical sufficient orientation must be required for calculating the curve of demagnetization. By comparing calculated and measured values, defects of the base materials, grindet powder, granulate, molding process, or magnetic orientation may be become known and removed.
