Effects of phonon - phonon coupling on low - lying states in neutron - rich Sn isotopes
نویسنده
چکیده
Starting from an effective Skyrme interaction we present a method to take into account the coupling between oneand two-phonon terms in the wave functions of excited states. The approach is a development of a finite rank separable approximation for the quasiparticle RPA calculations proposed in our previous work. The influence of the phonon-phonon coupling on energies and transition probabilities for the low-lying quadrupole and octupole states in the neutron-rich Sn isotopes is studied.

Relativistic RPA plus phonon-coupling analysis of pygmy dipole resonances
The relativistic random-phase approximation (RRPA) plus phonon-coupling (PC) model is applied in the analysis of E1 strength distributions in 208Pb and 132Sn, for which data on pygmy dipole resonances (PDR) have recently been reported. The covariant response theory is fully consistent: the effective nuclear interaction NL3 is used both to determine the spectrum of single-nucleon Dirac states, a...
متن کاملPygmy Dipol Resonances as a Manifestation of the Structure of the Neutron-Rich Nuclei
Dipole excitations in neutron-rich nuclei below the neutron threshold are investigated. The method is based on Hartree-Fock-Bogoliubov (HFB) and Quasiparticle-Phonon Model (QPM) theory. Of our special interest are the properties of the low-lying 1 Pygmy Resonance and the two-phonon quadrupole-octupole 1 states in Sn-isotopes including exploratory investigations for the experimentally unknown ma...
متن کاملBeyond mean-field theory in nuclei at the drip lines
Models based on particle-vibration coupling have been applied for many years to the study of single-particle states and giant resonances (GR) in stable nuclei, and are quite well established. In particular, in the last decade we have developed, within a Milano-Orsay collaboration, a microscopic model aimed to a detailed description of GR excitation and decay. In the present contribution, we dis...
متن کاملIsotopic dependence of the pygmy dipole resonance
The isotopic dependence of the excitation energies of the pygmy dipole resonance (PDR) is analyzed in the framework of the self-consistent relativistic HartreeBogoliubov (RHB) model and the relativistic quasiparticle random-phase approximation (RQRPA). The DD-ME1 density-dependent meson-exchange interaction is used in the effective mean-field Lagrangian, and pairing correlations are described b...

The properties of the low-energy dipole response are investigated for the proton-rich doubly magic nucleus 48 Ni, in a comparative study of two microscopic models: fully self-consistent Relativistic Random-Phase Approximation based on the novel density-dependent meson-exchange interactions, and self-consistent Continuum Random-Phase Approximation using Skyrme-type interactions with the continuu...
