Abstract
In the first paper with this title, a relation was derived from the available experimental data giving the Debye characteristic temperature of solid argon as a function of a (the interatomic distance) or V (the molal volume of the solid). This relation was not consistent with the usual Grüneisen assumption, which for a small range of volumes may be written approximately —Θ−1dΘ/dV=constant. In this paper it is shown that the Grüneisen assumption, with the constant set equal to 0.18 mole cc−1 is reasonably consistent with the experimental data. On this basis a new relation between the potential energy Ep of solid argon and a is derived. Most of the earlier conclusions are unaltered, but the present basis seems more reasonable, and, as will be shown in the following paper, avoids difficulties when application is made to liquid argon.
