“…The middle panel complements the excitation energies by the corresponding B(E2) values. These agree in the average fairly well with the experimental data (taken from [45,46,47,48,49,50,51,52,53]). However, there are substantial deviations in details: a dramatic drop at N=66 and 68 and a trend to overestimation towards shell closure N=82.…”

Abstract. The collective ground-state correlations stemming from low-lying quadrupole excitations are computed microscopically. To that end, the self-consistent mean-field model is employed on the basis of the Skyrme-Hartre-Fock (SHF) functional augmented by BCS pairing. The microscopic-macroscopic mapping is achieved by quadrupole-constrained mean-field calculations which are processed further in the generator-coordinate method (GCM) at the level of the Gaussian overlap approximation (GOA). We study the correlation effects on energy, charge radii, and surface thickness for a great variety of semi-magic nuclei. A key issue is to work out the influence of variations of the SHF functional. We find that collective ground-state correlations (GSC) are robust under change of nuclear bulk properties (e.g., effective mass, symmetry energy) or of spin-orbit coupling. Some dependence on the pairing strength is observed. This, however, does not change the general conclusion that collective GSC obey a general pattern and that their magnitudes are rather independent of the actual SHF parameters.

“…An alternative way to determine B(E1) strengths in particular for states of rare isotopes, for which NRF measurements are difficult, are lifetime measurements using the Doppler-shift attenuation method (DSAM) in particle-γ coincidence measurements [50]. Since several years, the DSAM technique is applied in inelastic neutron-scattering at the University of Kentucky [51,52]. Furthermore, direct access to the ground-state decay width Γ 0 can be obtained using the self-absorption method [53] or inelastic proton-scattering experiments [54] for some cases.…”
