Abstract
We show that Shaw's optimized nonlocal model potential (OMP) in combination with the perturbative hyper-netted-chain equation for pair correlation functions can be successfully applied to predict pair structures of compressed and expanded liquid rubidium. For compressed rubidium, it is possible to apply the OMP to a state for which the model radius is even close to the Wigner-Seitz radius. In addition, our results are parallel to those from Chihara and Kahl's quantal hypernetted-chain equation in that it supports the uniform compression model up to 6.1 GPa. Calculation also shows that the pair structure is relatively insensitive to the choice of the exchange-correlation function for the electron liquid. Discussions are also given for compressed and expanded cesium.
