“…However, new data on GMR in Sn isotopes [70,71] reopened the question of K o , as models which successfully predicted GMR energies in 90 Zr, 144 Sm, and 208 Pb could not reproduce GMR energies reported for [112][113][114][115][116][117][118][119][120][121][122][123][124] Sn. We note that the new GMR energies for 112,116,124 Sn do not agree (just outside errors) with previous data [72,73]. It has been suggested that the new measurement by Li et al offered cleaner spectra with less need for subtraction of background, which may possibly help to understand this discrepancy [71].…”

Skyrme interaction and nuclear matter constraints

et al. 2012

This paper presents a detailed assessment of the ability of the 240 Skyrme interaction parameter sets in the literature to satisfy a series of criteria derived from macroscopic properties of nuclear matter in the vicinity of nuclear saturation density at zero temperature and their density dependence, derived by the liquid-drop model, in experiments with giant resonances and heavy-ion collisions. The objective is to identify those parametrizations which best satisfy the current understanding of the physics of nuclear matter over a wide range of applications. Out of the 240 models, only 16 are shown to satisfy all these constraints. Additional, more microscopic, constraints on the density dependence of the neutron and proton effective mass β-equilibrium matter, Landau parameters of symmetric and pure neutron nuclear matter, and observational data on high-and low-mass cold neutron stars further reduce this number to 5, a very small group of recommended Skyrme parametrizations to be used in future applications of the Skyrme interaction of nuclear-matter-related observables. Full information on partial fulfillment of individual constraints by all Skyrme models considered is given. The results are discussed in terms of the physical interpretation of the Skyrme interaction and the validity of its use in mean-field models. Future work on application of the Skyrme forces, selected on the basis of variables of nuclear matter, in the Hartree-Fock calculation of properties of finite nuclei, is outlined.

“…The multipole decomposition analysis makes it possible to extract from the scattering data the strength associated with different multipolarities, in particular those corresponding to monopole and quadrupole. From these strengths, the position and width of the ISGMR and ISGQR peaks can be determined [88][89][90][91].…”

“…In Table VII we display the theoretical scaled and constrained estimates (including pairing) of E GMR of the nuclei 144 Sm, 208 Pb, 90 Zr, 112-124 Sn, and 106,[110][111][112][113][114][115][116] Cd together with the corresponding experimental values [88][89][90][91]. These estimates are given byĒ 3 andĒ 1 , respectively, defined previously, which, as mentioned, fulfillĒ 3 >Ē 1 (see the Appendix).…”

“…In Table VII we display the scaled energies of the quadrupole excitation computed with BCPM for several nuclei together with the available experimental values [88][89][90]104]. Insofar as the focus with a KS-DFT approach is on ground-state properties, we may not worry about the failure in the estimate of the ISGQR.…”

New Kohn-Sham density functional based on microscopic nuclear and neutron matter equations of state

et al. 2013

A new version of the Barcelona-Catania-Paris energy functional is applied to a study of nuclear masses and other properties. The functional is largely based on calculated ab initio nuclear and neutron matter equations of state. Compared to typical Skyrme functionals having 10-12 parameters apart from spin-orbit and pairing terms, the new functional has only 2 or 3 adjusted parameters, fine tuning the nuclear matter binding energy and fixing the surface energy of finite nuclei. An energy rms value of 1.58 MeV is obtained from a fit of these three parameters to the 579 measured masses reported in the Audi and Wapstra [Nucl. Phys. A 729, 337 (2003)] compilation. This rms value compares favorably with the one obtained using other successful mean field theories, which range from 1.5 to 3.0 MeV for optimized Skyrme functionals and 0.7 to 3.0 for the Gogny functionals. The other properties that have been calculated and compared to experiment are nuclear radii, the giant monopole resonance, and spontaneous fission lifetimes.
