LOCV CALCULATIONS OF PRESSURE IN NUCLEAR-MATTER AT FINITE-TEMPERATURE

The lowest-order constrained variational method is used to calculate t he equation of state of hot nuclear matter. The calculations are perfo rmed for a wide range of densities of interest in heavy-ion collisions and astrophysics. A realistic nuclear Hamiltonian that contains N-N a nd N-DELTA interactions and fits N-N scattering as well as nuclear mat ter saturation data is used. Besides spin, isospin, total angular mome ntum and density dependence, the correlation functions are also arrang ed to depend on the temperature of the system. The liquid-vapour, phas e equilibrium, as well as the behaviour of the effective mass in nucle ar matter, is discussed.
