“…The root mean square nuclear charge radii r 2 1/2 resulting from elastic electron scattering measurements have been reported by Briscoe et al [39] for both isotopes r 2 1/2 37 = 3.384 (15) (18) fm rms-value extracted from earlier muonic X-ray measurements [40]. To evaluate the difference δ r 2 35,37 = r 2 37 − r 2 35 appearing in (12), we choose for consistency, the two above values recommended by Briscoe et al [39] and also adopted in De Vries et al's compilation [41], ie. δ r 2 35,37 = −0.03(24) fm 2 .…”

Abstract. Today, the electron affinity is experimentally well known for most of the elements and is a useful guideline for developing ab initio computational methods. However, the measurements of isotope shifts on the electron affinity are limited by both resolution and sensitivity. In this context, theory eventually contributes to the knowledge and understanding of atomic structures, even though correlation plays a dominant role in negative ions properties and, particularly, in the calculation of the specific mass shift contribution. The present study solves the longstanding discrepancy between calculated and measured specific mass shifts on the electron affinity of chlorine [Phys. Rev. A 51, 231 (1995)].

Relativistic nuclear energy density functional constrained by low-energy QCD

et al. 2006

View full text Add to dashboard Cite

A relativistic nuclear energy density functional is developed, guided by two important features that establish connections with chiral dynamics and the symmetry breaking pattern of low-energy QCD: a) strong scalar and vector fields related to inmedium changes of QCD vacuum condensates; b) the long-and intermediate-range interactions generated by one-and two-pion exchange, derived from in-medium chiral perturbation theory, with explicit inclusion of ∆(1232) excitations. Applications are presented for binding energies, radii of proton and neutron distributions and other observables over a wide range of spherical and deformed nuclei from 16 O to 210 P o. Isotopic chains of Sn and P b nuclei are studied as test cases for the isospin dependence of the underlying interactions. The results are at the same level of quantitative comparison with data as the best phenomenological relativistic mean-field models.

“…In the CC calculation of the (α, α ′ ) process, we include all the six states listed above; we use the experimental values of the excitation energies. For the ground state density of α, we take the phenomenological one determined from electron scattering [11] in which the finite-size effect of proton charge is unfolded with a standard procedure [12].…”

The Hoyle state of 12 C has intensively been studied theoretically and experimentally. Despite a rather clear understanding of its three-α cluster structure, the description of the Hoyle state appeared in reaction observables has not been achieved. It was reported in many studies that the (α,α ′ ) cross section theoretically obtained with using the transition density of 12 C from the ground state to the 0 + 2 state significantly overshot the measured cross section. This discrepancy is called the missing monopole strength of the Hoyle state. To solve this probelm, we apply a fully microscopic framework to the (α,α ′ ) inelastic scattering to the 0 + 2 state of 12 C, and show that the calculated result agrees with the measured cross section. We find the consistency between the monopole strength of the Hoyle state determined by structural calculation and that extracted from reaction observables. We thus show essentially there is no room for the missing monopole strength.
