Theoretical investigations of isoscalar, isovector and mixed symmetry states in skin nuclei

چکیده
Abstract. We present recent investigations on dipole and quadrupole excitations in spherical skin nuclei, particular exploring their connection to the thickness of the neutron skin. Our theoretical method relies on density functional theory, which provides us with a proper link between nuclear many-body theory of the nuclear ground state and its phenomenological description. For the calculation of the nuclear excited states we apply QPM theory. A new quadrupole mode related to Pygmy Quadrupole Resonance in tin isotopes is suggested.

Dipole response in neutron-rich nuclei with new Skyrme interactions
We investigate the isoscalar and isovector E1 response of neutron-rich nuclei, within a semiclassical transport model employing effective interactions for the nuclear mean-field. In particular, we adopt the recently introduced SAMi-J Skyrme interactions, whose parameters are specifically tuned to improve the description of spin-isospin properties of nuclei. Our analysis evidences a relevant deg...
متن کاملIsospin asymmetry in nuclei and nuclear symmetry energy
Binding energy of isospin asymmetric nuclei can be accessed with minimally modified formula along the lines of the liquid droplet model by partitioning the symmetry term into volume and surface terms. The volume symmetry energy coefficient extracted from finite nuclei provides a constraint on the nuclear symmetry energy. This approach also yields the neutron skin of a finite nucleus through its...
متن کاملCranking in Isospace - towards a Consistent Mean-field Description of N = Z Nuclei
Excitation spectra ∆ET of T = 0, 1, 2 states in even-even (e-e) and odd-odd (o-o) N = Z nuclei are analyzed within a mean-field based model involving isovector and isoscalar pairing interactions and the iso-cranking formalism applied to restore approximately isospin symmetry. It is shown that T = 0 states in o-o and T = 1 states in e-e nuclei correspond to two-quasiparticle, time-reversal symme...
متن کاملRoles of isoscalar hyperons in probing the density dependence of the nuclear symmetry energy
The role of the isoscalar hyperon Λ in probing the density dependence of the nuclear symmetry energy is studied in multi-Λ hypernuclei, hyperon-rich matter and neutron stars in relativistic models. Relationships between the properties of three types of objects and the neutron thickness in Pb are established with respect to the isoscalar-isovector coupling that modifies the density dependence of...
متن کاملPairing and isospin symmetry in proton-rich nuclei
Unlike their lighter counterparts, most odd-odd N = Z nuclei with mass A > 40 have ground states with isospin T=1, suggesting an increased role for the isovector pairing interaction. A simple SO(5) seniority-like model of this interaction reveals a striking and heretofore unnoticed interplay between likeparticle and neutron-proton isovector pairing near N = Z that is reflected in the number of ...
