Correlation of Geiger Counter and Hall Effect Measurements in Alloys Containing Germanium and Radioactive Antimony 124

The distribution of the solute atoms in ingots of germanium antimony alloys which were prepared according to a prescribed cooling cycle have been measured. The solute was ${\mathrm{Sb}}^{124}$ and its distribution was measured with a Geiger counter. In addition, Hall measurements were made which show that in the impurity saturation range each antimony atom contributes one conduction electron. This makes it possible to determine the solute distribution in non-radioactive samples by the Hall method.
