The thermodynamic and structural properties of the HS system play an essen-
tial role in some integral equation perturbation theories, as addressed in
Chapter 4, as well as in other kinds of perturbation theories that will be addressed
in Chapter 6. For this reason, in this chapter, after describing the different phases of
the HS system, we present a number of theories for the radial distribution function
and the EOS of the HS fluid and solid. Concerning the fluid, we will start with the
derivation of the scaled particle theory (SPT) which, although does not provide ...
