Density Dependent

Most of the Skyrme interactions are known to predict spin or isospin instabilities beyond the saturation density of nuclear matter which contradict predictions based on realistic interactions. A modification of the standard Skyrme interaction is proposed so that the ferromagnetic instability is removed. The new terms are density dependent and modify only the spin p - h interaction in the case of spin-saturated system.

Most of the Skyrme interactions are known to predict spin or isospin instabilities beyond the saturation density of nuclear matter which contradict predictions based on realistic interactions. A modification of the standard Skyrme interaction is proposed so that the ferromagnetic instability is removed. The new terms are density dependent and modify only the spin p - h interaction in the case of spin-saturated system. We have shown that these new terms change the total binding energy of odd-nuclei by only few tenths of keV. From the analysis of the spin instabilities of nuclear matter, restrictions on the parameters governing the spin-density dependent terms are evaluated. We conclude that with the extended Skyrme interaction, the Landau parameters G0 and [Formula: see text] could be tuned with a large flexibility without changing the ground-state properties in nuclei and in nuclear matter.

Neutrino Propagation

The neutrino propagation in asymmetric nuclear matter is studied in the framework of the linear response method. The medium effects are treated in the Hartree-Fock approach with an effective Skyrme interaction. The neutrino opacity for the nuclear matter has been calculated in a wide range of densities and temperatures.
