Symmetry energy , neutron star crust and neutron skin thickness ⋆
We analyze the correlations of the slope and curvature parameters of the symmetry energy with the neutron skin thickness of neutron-rich isotopes, and the crust-core transition density in neutron stars. The results are obtained within the microscopic Brueckner–Hartree–Fock approach, and are compared with those obtained with several Skyrme and relativistic mean field models.
متن کاملNuclear symmetry energy probed by neutron skin thickness of nuclei.
We describe a relation between the symmetry energy coefficients c(sym)(rho) of nuclear matter and a(sym)(A) of finite nuclei that accommodates other correlations of nuclear properties with the low-density behavior of c(sym)(rho). Here, we take advantage of this relation to explore the prospects for constraining c(sym)(rho) of systematic measurements of neutron skin sizes across the mass table, ...
متن کاملIs a neutron halo nothing but a large neutron skin?
In 1967, D. Wilkinson[1] suggested that in neutron rich nuclei, a few neutron might be loosely bound forming ”halos”. Though it was unclear what precisely was meant by this terms, in the ’80 the unusual result concerning the structures in longitudinal momentum distribution [2] in Li fragments from neutron rich Li led physicists[3] to consider the possibility of Li being one of these new “halo” ...
متن کاملNeutron skin of Pb in consistency with neutron star observations
The renormalized meson-nucleon couplings are applied to the relativistic optical model of p-208Pb elastic scattering at Tlab = 200MeV. We calculate the strength of the vector potential at nuclear center as varying the neutron radius of 208Pb. The neutron skin thickness Sn is determined in the comparison of the calculated potential with the phenomenological one. We nd a value Sn = 0:118fm being...
متن کاملneutron star density in vacuum
By simple arguments, we have shown that Károlyházy's model overestimates the quantum uncertainty of the space-time geometry and leads to absurd physical consequences. The given model can thus not account for gradual violation of quantum coherence and can not predict tiny experimental effects either.
