摘要：

For fermionic model systems with a separable interaction the BCS equations are solved self-consistently. In addition, the possibility of a liquid-gas phase transition is considered by inspecting thermodynamic stability. Different examples of temperature-density pll;ise diagrams are given depending on the parameters of a model interaction. In particular, a liquid-gas binodal anomaly is found due to the superposition of the superfluid and the liquid-gas phase transition.
