Kaon condensation in neutron star using relativistic mean field models
We use the modified quark-meson coupling and the quantum hadrodynamics models to study the properties of neutron star. Coupling constants of both models are adjusted to reproduce the same saturation properties. The onset of kaon condensation in neutron star matter is studied in detail over a wide range of kaon optical potential values. Once the kaon condensation takes place, the population of k...
متن کاملNeutrino mean free path and in - medium nuclear interaction
Neutrinos produced during the collapse of a massive star are trapped in a nuclear medium (the proto-neutron star). Typically, neutrino energies (10-100 MeV) are of the order of nuclear giant resonances energies. Hence, neutrino propagation is modified by the possibility of coherent scattering on nucleons. We have compared the predictions of different nuclear interaction models. It turns out tha...

متن کاملNeutron Halos in Heavy Nuclei Relativistic Mean Field Approach
Assuming a simple spherical relativistic mean eld model of the nucleus, we estimate the width of the antiproton{neutron annihilation ( n) and the width of antiproton{proton ( p) annihilation, in an antiprotonic atom system. This allows us to determine the halo factor f , which is then discussed in the context of experimental data obtained in measurements recently done on LEAR utility at CERN. A...
متن کاملSelf-consistent relativistic calculation of nucleon mean free path.
We present a fully self-consistent and relativistic calculation of the nucleon mean free path in nuclear matter and finite nuclei. Starting from the Bonn potential, the Dirac-Brueckner-Hartree-Fock results for nuclear matter are parametrized in terms of an effective σ-ω Lagrangian suitable for the relativistic density-dependent Hartree-Fock (RDHF) approximation. The nucleon mean free path in nu...
