Abstract : The addition of metal to a metal-ammonia solution already in the metallic regime can lead to a further reduction in density. This experimental observation can be accounted for by a straightforward evaluation of the dominant volume-dependent and one-body terms contributing to the thermodynamic functions of the metallic state. Augmenting these terms are smaller two-body terms which are important in a structural sense. Because of the exceptionally low electron-densities found in metal-ammonia solutions, it is proposed that these can be significantly changed, in a state-dependent fashion, by inclusion of fluctuation effects.
