“…The calculated gaps in the former are larger than those in the latter, by about 4 MeV at the maximum, for example. This difference is brought about by that in the coupling constants rather than the Fock effect itself [38]. Actually we confirmed that a Hartree calculation with the coupling constants of the Hartree-Fock gave almost the same gaps as those given by the Hartree-Fock calculation although such a calculation destroys the saturation completely.…”

We construct phenomenologically a relativistic particle-particle channel interaction which suits the gap equation for nuclear matter. This is done by introducing a density-independent momentum-cutoff parameter to the relativistic mean field (Hartree and Hartree-Fock) models so as to reproduce the pairing properties obtained by the Bonn-B potential and not to change the saturation property. The interaction so obtained can be used for the Relativistic Hartree-Bogoliubov calculation, but some reservation is necessary for the Relativistic Hartree-Fock-Bogoliubov calculation.

“…The best value to use might be option e for the reasons discussed above. This choice is also recommended by Carlson [82]. Note, that in The experimental fitting results agree with the Gaussian shape, and significantly diverge from the dipole parameterization at momentum transfers ≥ 0.2 GeV.…”

Theory of the Lamb Shift and fine structure in muonic 4He ions and the muonic 3He– 4He Isotope Shift

We provide an up to date summary of the theory contributions to the 2S → 2P Lamb shift and the fine structure of the 2P state in the muonic helium ion (µ 4 He) + . This summary serves as the basis for the extraction of the alpha particle charge radius from the muonic helium Lamb shift measurements at the Paul Scherrer Institute, Switzerland. Individual theory contributions needed for a charge radius extraction are compared and compiled into a consistent summary. The influence of the alpha particle charge distribution on the elastic two-photon exchange is studied to take into account possible model-dependencies of the energy levels on the electric form factor of the nucleus. We also discuss the theory uncertainty which enters the extraction of the 3 He-4 He isotope shift from the muonic measurements. The theory uncertainty of the extraction is much smaller than a present discrepancy between previous isotope shift measurements. This work completes our series of n = 2 theory compilations in light muonic atoms which we have performed already for muonic hydrogen, deuterium, and helium-3 ions.

“…One reason is that they adopted coupling constants which reproduced the saturation in the Hartree-Fock approximation, not the Hartree (so-called MFT) approximation. This leads to larger pairing gaps [31]. The other reason is the difference in the evaluation of the Dirac sea effects.…”
