The minimum dipole moment, Dmin = 0.6393 eao = 1.625 × 10−18 esu-cm, required for electronic binding to a dipole has been found, weaker dipoles having no negative energy states.

Abrikosov's physically intuitive ansatz of superposing free flux lines in order to calculate the mixed state of type-II-superconductors at the lower critical field is shown to be mathematically exact for all κ >√2 in the framework of Ginzburg-Landau-theory.
A calculation of the heat of mixing in liquid alkali alloys is presented. The two-body correlation function is used for the calculation. The theoretical value is satisfactorily comparable to the experimental one in the Na-K system.
On extraction of negative ions from a metal vapour plasma of a Penning discharge, the existence of Be−, BeH−, Mg− and MgH− ions could be demonstrated. The currents produced were sufficient for an acceleration of these ions.
The observation of molecular ringing in a single cavity ammonia beam maser is reported. The technique used is that of rapid passage of an exciting signal through the molecular emission line.
It is shown that contrary to the opinion given in a recent letter [1] the anomalous behaviour of the Hall coefficient for NiO at high temperatures cannot be interpreted in terms of native-defect structure.
New bands, associated with cesium forbidden lines, appear in absorption spectra of cesium with atmospheric pressure of xenon. They are not seen clearly with lighter noble gases or at reduced xenon pressures and are ascribed to collision enforced transitions.
Thin CdS-single crystals in darkness show current-voltage characteristics in agreement with Lampert's theory. Illumination with photons in the extrinsic energy-range appears to increase considerably the amount of injected charge that remains free in the conduction band.
The infrared absorption spectrum (250 to 4000 cm−1) of NH4H2PO4 was taken above and below the Curie temperature. Suggestions are put forward as to the hydrogen ordering in the antiferroelectric phase.
Data are presented to show that |K1| of magnetite decreases with decreasing Fe2+ content. Recently published results which indicate an opposite behavior are discussed.
