Abstract
The observed structure factors of expanded liquid rubidium (for temperatures up to 1900K and pressures up to 122 bar near saturation conditions) can be explained using (a) nearly-free electron theory to describe the interatomic forces and then (b) standard techniques of classical liquid theory to deduce the corresponding structures. The high-K observations correspond to close binary collisions involving atomic cores of fairly hard-sphere character, while the low-K behaviour can be described by long-wavelength density fluctuations, the description of which requires, in addition, the use of the interatomic potential tails.Keywords
