    "abstract": "An effective method based on Hubbard-Schofield approach [Phys. Lett. A {\\bf\n40}, 245 (1972)] is developed to calculate the free energy of classical Coulomb\nsystems. This method significantly simplifies the derivation of the cluster\nexpansion. A diagrammatic representation of the cluster integrals is proposed.\nSimple rules providing the leading order in density $n$ of each diagrammatic\ncontribution are found. We calculate the $n^3$ contribution and recover the\nresults at the order $n^{5/2}$ obtained by the traditional method of\nresummation of diverging Mayer bonds.",
