We present a theoretical model for calculating the thermodynamic properties of liquid C60
by means of an improved equation of state (EOS), in which the particles interact via pairwise
interaction composed of hard-core plus suitable linear combinations of three Yukawa
functions. The proposed EOS provides simple analytical expressions for Helmholtz free
energy and pressure, which are the basic ingredients to compute the liquid–vapour
coexistence curve of C60 as well as all other thermodynamic properties for the bulk liquid ...
