Effects of self-consistency violation in Hartree-Fock RPA calculations for nuclear giant resonances revisited
نویسنده
چکیده
We provide accurate assessments of the consequences of violations of self-consistency in HartreeFock (HF) based random phase approximation (RPA) calculations of the centroid energy Ecen of isoscalar and isovector giant resonances of multi-polarities L = 0 − 3 in a wide range of nuclei. This is done by carrying out highly accurate HF-RPA calculations neglecting the particle-hole (ph) spin-orbit or Coulomb interaction in the RPA and comparing with the fully self-consistent HF-RPA results. We find that the shifts in the value of Ecen due to self-consistency violation associated with the spin-orbit and Coulomb interactions are comparable or larger than the current experimental errors in Ecen. PACS numbers: 24.30.Cz, 21.65.+f, 21.60.Jz

Self-Consistent Hartree-Fock Based Random Phase Approximation And The Spurious State Mixing
We use a fully self-consistent Hartree−Fock (HF) based continuum random phase approximation (CRPA) to calculate strength functions S(E) and transition densities ρt(r) for isoscalar giant resonances with multipolarities L = 0, 1 and 2 in 80Zr nucleus. In particular, we consider the effects of spurious state mixing (SSM) in the isoscalar giant dipole resonance (ISGDR) and extend the projection me...
متن کاملGiant Resonances from Tdhf
It is well-known that the Random Phase Approximation (RPA) is equivalent to Time-Dependent Hartree-Fock (TDHF) to first order in the density fluctuations from the static Hartree-Fock ground state. Therefore either approach may be used to calculate giant resonance states in nuclei. Historically, the RPA approach has been more popular, particularly working directly in the response function formal...
متن کاملGiant resonances in exotic spherical nuclei within the RPA approach with the Gogny force
Theoretical results for giant resonances in the three doubly magic exotic nuclei Ni, Sn and Sn are obtained from Hartree-Fock (HF) plus Random Phase Approximation (RPA) calculations using the D1S parametrization of the Gogny two-body effective interaction. Special attention is paid to full consistency between the HF field and the RPA particle-hole residual interaction. The results for the exoti...

We have studied the core-polarization effect on the IsOd-she11 single-particle electromagnetic quadrupole transitions due to coupling with the quadrupole giant resonances. The self-consistent Hartree-Fock + RPA method is applied for the calculations of the single-particle wave functions and the response functions of the giant resonances. The particle-vibration-coupling model is used to calculat...
متن کاملNuclear Giant Resonances and Linear Response
We search for nonlinear effects in nuclear giant resonances (GRs), in particular the isovector dipole and the isoscalar quadrupole modes. To that end, we employ a spectral analysis of time-dependent Hartree-Fock (TDHF) dynamics using Skyrme forces. Based on TDHF calculations over a wide range of excitation amplitudes, we explore the collectivity and degree of harmonic motion in these modes. Bot...
