Title: Nuclear dipole polarizability from mean-field modeling constrained by chiral effective field theory

Abstract

We construct a new Skyrme interaction Skχm* by fitting the equation of state and nucleon effective masses in asymmetric nuclear matter from chiral two- and three-body forces as well as the binding energies of finite nuclei. Employing this interaction to study the electric dipole polarizabilities of ⁴⁸Ca, ⁶⁸Ni, ¹²⁰Sn, and ²⁰⁸Pb in the random-phase approximation, we find that the theoretical predictions are in good agreement with experimentally measured values without additional fine tuning of the Skyrme interaction, thus confirming the usefulness of the new Skyrme interaction in studying the properties of nuclei. We further use this interaction to study the neutron skin thicknesses of ⁴⁸Ca and ²⁰⁸Pb, and they are found to be consistent with the experimental data.

Electric dipole polarizability and the neutral skin

Journal Article Piechaczek, A. ; Nazarewicz, Witold ; Reinhard, P. -G. ; ... - Physical Review C

The recent high-resolution measurement of the electric dipole (E1) polarizability {alpha}{sub D} in {sup 208}Pb [A. Tamii et al. Phys. Rev. Lett. 107 062502 (2011)] provides a unique constraint on the neutron-skin thickness of this nucleus. The neutron-skin thickness r{sub skin} of {sup 208}Pb is a quantity of critical importance for our understanding of a variety of nuclear and astrophysical phenomena. To assess the model dependence of the correlation between {alpha}{sub D} and r{sub skin}, we carry out systematic calculations for {sup 208}Pb, {sup 132}Sn, and {sup 48}Ca based on the nuclear density functional theory using both nonrelativistic and relativisticmore »« less
Charge Radius of the Short-Lived ${}^{68}{Ni}$ and Correlation with the Dipole Polarizability

Journal Article Kaufmann, S. ; Simonis, J. ; Bacca, S. ; ... - Physical Review Letters

We present the first laser spectroscopic measurement of the neutron-rich nucleus ⁶⁸Ni at the N = 40 subshell closure and extract its nuclear charge radius. Since this is the only short-lived isotope for which the dipole polarizability $α$_D has been measured, the combination of these observables provides a benchmark for nuclear structure theory. We compare them to novel coupled-cluster calculations based on different chiral two- and three-nucleon interactions, for which a strong correlation between the charge radius and dipole polarizability is observed, similar to the stable nucleus ⁴⁸Ca. Three-particle–three-hole correlations in coupled-cluster theory substantially improve the description of the experimentalmore »« less

Computing the dipole polarizability of ${}^{48}{Ca}$ with increased precision

Journal Article Miorelli, Mirko ; Bacca, S. ; Hagen, Gaute ; ... - Physical Review C

Here, we compute the electric dipole polarizability of ⁴⁸Ca with an increased precision by including more correlations than in previous studies. Employing the coupled-cluster method we go beyond single and double excitations and include leading-order three-particle-three-hole (3p-3h) excitations for the ground state, excited states, and the similarity-transformed operator. We study electromagnetic sum rules, such as the bremsstrahlung sum rule m₀ and the polarizability sum rule αD using interactions from chiral effective field theory. To gauge the quality of our coupled-cluster approximations we perform several benchmarks with the effective interaction hyperspherical harmonics approach in ⁴He and with self consistent Green's functionmore »« less

Electric Dipole Polarizability of ${}^{48}{Ca}$ and Implications for the Neutron Skin

Journal Article Birkhan, J. ; Miorelli, M. ; Bacca, S. ; ... - Physical Review Letters

The electric dipole strength distribution in ⁴⁸Ca between 5 and 25 MeV has been determined at RCNP, Osaka, from proton inelastic scattering experiments at forward angles. Combined with photoabsorption data at higher excitation energy, this enables the rst extraction of the electric dipole polarizability D(⁴⁸Ca) = 2:07(22) fm³. Remarkably, the dipole response of ⁴⁸Ca is found to be very similar to that of ⁴⁰Ca, consistent with a small neutron skin in ⁴⁸Ca. The experimental results are in good agreement with ab initio calculations based on chiral e ective eld theory interactions and with state-of-the-art density-functional calculations, implying a neutron skinmore » in ⁴⁸Ca of 0:14 - 0:20 fm.« less

Neutron-skin thickness of finite nuclei in relativistic mean-field models with chiral limits

Journal Article Weizhou, Jiang ; Institute of Applied Physics, Chinese Academy of Sciences, Shanghai 201800 ; Baoan, Li ; ... - Physical Review. C, Nuclear Physics

We study several structure properties of finite nuclei using relativistic mean-field Lagrangians constructed according to the Brown-Rho scaling due to the chiral symmetry restoration at high densities. The models are consistent with current experimental constraints for the equations of state of symmetric matter at both normal and supranormal densities and of asymmetric matter at subsaturation densities. It is shown that these models can successfully describe the binding energies and charge radii of finite nuclei. Compared to calculations with usual relativistic mean-field models, these models give a reduced thickness of neutron skin in {sup 208}Pb between 0.17 fm and 0.21 fm.more »« less
