On the Excess Entropy of Liquid Alkali Metals

抄録

Analytic expressions for the excess entropy in the hard-sphere system, the charged-hard-sphere (CHS) system and the classical one-component plasma (OCP) are summarised. The excess entropy of liquid alkali metals is discussed in relation to these model systems. It is shown that, to reproduce the observed excess entropy, a significantly reduced values of plasma parameter have to be used in the CHS system as well as in the OCP.
