Hot nuclear matter in the static fluctuation approximation

In this work, the bulk and thermodynamic properties of nonrelativistic hot nuclear matter--the mean internal energy per unit volume, the saturation density and the corresponding internal energy per nucleon, the pressure, the entropy per unit volume, the heat capacity per unit volume, and the chemical potential--are studied within the static fluctuation approximation (SFA). The basic input is the well-known Reid68 and Reid93 soft-core potentials, with special emphasis on three channels that have different spin and isospin--namely, the 1S0-channel as well as the 3S1-3D1 and 3P2-3F2 coupled channels. Finally, a full-fledged calculation is presented using the Reid93 potential for all channels J≤2. Wherever possible, comparisons are made with previous calculations. It is concluded that SFA is valid for hot nuclear matter over a wide range of temperatures (≤50 MeV)
