Abstract
For the quantitative evaluation of neutron diffraction experiments and other physical measurements of molten metals and alloys the knowledge of the density is important. Furthermore the molar volume which is directly connected with the density represents itself a physical quantity which is essential for the discussion of structural results. Different methods for the experimental determination of the density of melts were discussed in Refs. 1, 2. In the present paper the density of Au-Cs-melts was determined by the method of γ-absorption which has the advantage to need only small specimens and furthermore allows the specimen to be enclosed in a vacuum tight container during the measurement.
