“…and in many of them this creates a problem in the description of the kink in charge radii at N = 126 4. The averaged slopes for the N < 126 nuclei are almost the same in the calculations with and without pairing (see Ref [92]. for detail).…”

“…First, the nodal structure of the wavefunctions and neutron radius of the single-neutron orbital depend on its quantum numbers such as total and orbital angular momenta (see Refs. [3,5,92]). Thus, the occupation of different neutron single-particle states impacts the resulting charge radii (see Refs.…”

“…Ref. [29] argued that the pairing correlation reduces the charge radius kink at N > 126 based on the covariant density functional theory. Because in the covariant density functional theory the 0i 11/2 energy is lower than the 1g 9/2 one, the occupation number of the 0i 11/2 orbit is reduced when the pairing interaction is included, which is in contrast to the present Skyrme density functional cases.…”

We revisit a sudden increase of the isotope shift of the charge radius of Pb isotope at N > 126 based on a Skyrme Hartree-Fock-Bogoliubov theory. New parametrizations of the pairing interaction optimized for selected four Skyrme interactions greatly improve a description of this phenomenon. The density-dependent spin-orbit interaction is also investigated and further increases the charge radius. The pairing correlations significantly change the properties of the neutron orbits near the Fermi level and play a vital role in pulling out the well-bound protons in the Pb isotopes at N > 126. Regarding 208 Pb as a "core" nucleus, a novel pairing core swelling effect is proposed: The pairing interaction reduces the radius of "valence" neutron orbits by the shrinkage of diffused 1g 9/2 orbit and the mixing of sharp 0i 11/2 orbit. Simultaneously, the core nucleus swells, leading to the sudden enhancement of the charge radius at N > 126. This characteristic behavior appears in the density profile near the nuclear surface and its measurement is highly desirable.

“…Other explanations than octupole phenomena in lower-Z nuclei are considered in Ref. [30], which also mentions the possibility that collective vibrational effects might similarly produce IDNCR. For some isotopes, IDNCR is the only experimental information, yet thought it can be consistent with static octupole deformation or collective octupole vibrations, unfortunately can't be definitive.…”

This is a resource paper concerning enhancement of observable time-reversal breaking effects by nuclear structure, aimed at AMO experimentalists. It's intended to support a white paper [1] by providing some orientation on what can be said about some particular isotopes. Any conclusions are qualitative, and the reader should consult and cite the primary references and reviews rather than this arXiv alone.
