“…[9] for 208 Pb we extract a range of 235-250 MeV. Thus, all these relativistic calculations point to a value of roughly 250 ± 20 MeV for K ∞ , which is higher than the nonrelativistic estimate of 215 ± 15 MeV from Skyrme and Gogny forces [47,48]. Relativistic parameter sets with large values of K ∞ (such as NL-SH or NL2), which may otherwise perform well in describing the data for nuclear masses and radii, should be discarded on the basis of the experimental information on breathing-mode energies.…”

“…[31,220] The calculations of Sec. 5.5 employ a bare interaction V αβ,γδ for the vertices K (pp) and K (ph) so that the Bethe-Salpeter equations (154) reduce to the usual dressed RPA (DRPA) equations [32,221]. The solutions of these equations depend only on two times.…”

Recent results obtained by applying the method of self-consistent Green's functions to nuclei and nuclear matter are reviewed. Particular attention is given to the description of experimental data obtained from the (e,e ′ p) and (e,e ′ 2N) reactions that determine one and two-nucleon removal probabilities in nuclei since the corresponding amplitudes are directly related to the imaginary parts of the single-particle and two-particle propagators. For this reason and the fact that these amplitudes can now be calculated with the inclusion of all the relevant physical processes, it is useful to explore the efficacy of the method of self-consistent Green's functions in describing these experimental data. Results for both finite nuclei and nuclear matter are discussed with particular emphasis on clarifying the role of short-range correlations in determining various experimental quantities. The important role of long-range correlations in determining the structure of lowenergy correlations is also documented. For a complete understanding of nuclear phenomena it is therefore essential to include both types of physical correlations. We demonstrate that recent experimental results for these reactions combined with the reported theoretical calculations yield a very clear understanding of the properties of all protons in the nucleus. We propose that this knowledge of the properties of constituent fermions in a correlated many-body system is a unique feature of nuclear physics.

The status of the theoretical research on the compressional modes of finite nuclei and the incompressibility K ∞ of nuclear matter, is reviewed. It is argued that the recent experimental data on the Isoscalar Giant Monopole Resonance (ISGMR) allow extracting the value of K ∞ with an uncertainity of about ± 12 MeV. Non-relativistic (Skyrme, Gogny) and relativistic mean field models predict for K ∞ values which are significantly different from one another, namely ≈ 220-235 and ≈ 250-270 MeV respectively. It is shown that the solution of this puzzle requires a better determination of the symmetry energy at, and around, saturation. The role played by the experimental data of the Isoscalar Giant Dipole Resonance (ISGDR) is also discussed.
