Abstract
Landau's theory for normal Fermi liquids is applied in nuclear matter. The quasiparticle interaction and physical quantities related to this are calculated. We apply a method, previously used by Babu and Brown, where the interaction through the polarization of the medium around a quasiparticle is accounted for. This so-called induced interaction is repulsive and has a tendency to compensate for changes in the (mainly) attractive direct interaction and hence ensures a stability in the total interaction. Another advantage is that the Pauli principle is automatically satisfied. We calculate the direct interaction within the framework of the Brueckner-Bethe theory using the Reid soft-core potential for the bare nucleon-nucleon interaction. For the quasiparticle effective mass m ∗ , the symmetry energy β and the compression modulus K values of 0.77 m, 25.6 MeV and 184 MeV, respectively, were obtained.
