“…2 with the experimental one found in Ref. [13] with the modelindependent analysis of the high-precision data on the elastic electron scattering. It is worth mentioning that these two figures confirm the interpretation by Khodel [14,8] of the 2 + 1 -excitations as quantum capillary waves belonging to the Goldstone branch of surface vibrations.…”

Abstract. Excitation energies and transition probabilities of the first 2+ excitations in even lead, tin and nickel isotopes are calculated within the self-consistent Theory of Finite Fermi Systems based on the Energy Density Functional by Fayans et al. A reasonable agreement with available experimental data is obtained. The effect of the density dependence of the effective pairing interaction is analyzed in detail by comparing results obtained with volume and surface pairing. The effect is found to be noticeable, especially for the 2 + -energies which are systematically higher at 200-300 keV for the volume paring as compared with the surface pairing case, the latter being in a better agreement with the data.

“…In conclusion of this Section we compare in Fig. 14 the charge transition density ρ tr ch (r) in the 118 Sn nucleus with the experimental transition charge density found with a model independent analysis of the elastic electron scattering in [46]. The theoretical charge density is obtained from ρ tr p (r) and ρ tr n (r) functions displayed in Fig.…”

Effects of density dependence of the effective pairing interaction on the first2+excitations and quadrupole moments of odd nuclei

Excitation energies and transition probabilities of the first 2 + excitations in even tin and lead isotopes as well as the quadrupole moments of odd neighbors of these isotopes are calculated within the self-consistent Theory of Finite Fermi Systems based on the Energy Density Functional by Fayans et al. The effect of the density dependence of the effective pairing interaction is analyzed in detail by comparing results obtained with volume and surface pairing. The effect is found to be noticeable. For example, the 2 + -energies are systematically higher at 200-300 keV for the volume paring as compared with the surface pairing case. But on the average both models reasonably agree with the data. Quadrupole moments of odd-neutron nuclei are very sensitive to the single-particle energy of the state λ under consideration due to the Bogolyubov factor (u 2 λ − v 2 λ ). A reasonable agreement with experiment for the quadrupole moments has been obtained for the most part of odd nuclei considered. The method used gives a reliable possibility to predict quadrupole moments of unstable odd nuclei including very neutron rich ones.

Differential cross sections for electron scattering from ' Sr have been measured for excited states below 3.5 MeV over a range of effective momentum transfer of 0.4 to 2.8 fm '. The elastic scattering data have been analyzed to reconstruct the ground-state charge distribution. The inelastic scattering data have been analyzed to extract transition charge densities. Interpretation of the underlying nuclear structure is given in the framework of a self-consistent finite Fermi system theory.
