摘要：

Starting from a quantum statistical approach to the the density-density response function, its relation to the compressibility and to the equation of state of nuclear matter at finite temperature is investigated. In particular, the contribution of two-particle correlations to the dynamical structure factor is taken into account, which becomes important at low temperatures in the low-density limit. It is shown that this treatment for the structure factor is consistent with the equation of state up to the second virial coefficient.
