The Magnetic Susceptibilities of Metals Dissolved in Liquid Ammonia

Here are recorded data on the magnetic susceptibilities of potassium and of cesium dissolved in liquid ammonia at 240°K and 220°K. Also included are a few data on calcium and barium. These solutions throughout the entire range of concentrations were regarded as representing an electron gas. Such systems would permit the distributions of the magnetic moments of the electrons to be followed continuously from the degenerate region of the Fermi‐Dirac statistics to those distributions where the quantum and classical statistics are indistinguishable. The general features of the magnetic behavior of a free electron gas were recognized, overlaid, however, by interactions characteristic of the environment of the electrons in the solutions. In the light of the magnetic susceptibilities as well as of other properties, a description is proposed for the structure of the solutions with special reference to the conduction electrons. Barium was found to dissociate into two electrons per gram atom and it is inferred that ...

The Magnetic Susceptibility of Silver Sub‐Fluoride

The metallic character of the crystals of silver sub‐fluoride was studied in terms of the magnetic susceptibility. It was found that the conduction electrons contribute a considerable diamagnetism which was related especially to the anisotropy of the crystals.

Interchange of Fission‐Product Bromine with Carrier Bromine

Experiments on the interchange of the fission products 2.4‐hr Br83 and 55.6‐sec Br87 with carrier bromine have been performed. Essentially the same degree of interchange is effected by the following chemical procedures: carrier added as BrO3− and reduced by H2S, carrier added as BrO3− and reduced by excess carrier Br−, and carrier added as Br− to HCl and irradiated uranium metal dissolved.
