Spectral and thermodynamical properties of symmetric nuclear matter with Gogny interaction

The finite ranges effect of an effective force on the single particle properties and the particle-hole effective interaction are investigated in a wide interval of temperatures. The calculations are performed in a framework of a thermal Hartree-Fock method using the D1-Gogny density dependent intera...
