Abstract
We study statistical mechanics of the self-gravitating system applying the cluster expansion method developed in solid state physics. By summing infin ite series of diagrams, we derive a complex free energy whose imaginary par t is related to the relaxation time of the system, and a two-point correlat ion function.
