Electric and Magnetic Moments and Transition Probabilities in $^{208}$Pb $\pm 1$ Nuclei

Abstract

We present moments and transition probabilities in the neighboring odd-mass nuclei of 208 Pb calculated fully self-consistently from the s.p. properties of 208 Pb with polarization corrections from its excitations, both given from previous Skyrme-Hartree-Fock and RPA calculations. The electric results agree nicely with the data with two very interesting exceptions. In the magnetic case we obtain similar results. We discuss also polarization contributions to the l-forbidden M 1 transitions, which are, however, much too small compared to the data. With a modified external field operator which accounts effectively for mesonic and many-body effects the description of the data can be substantially improved.

Nuclear DFT analysis of electromagnetic moments in odd near doubly magic nuclei

“…Establishing the baseline for including analogous corrections to the magnetic-moment operator is, therefore, of paramount importance. The deformed DFT approach is probably close to a spherical quasiparticle-phonon interaction method [32][33][34][35][36][37][38], with an explicit coupling of spherical quasiparticles and phonons replaced by the use of symmetry-restored deformed DFT configurations. However, a dedicated comparative analysis of prospective links is not available yet.…”
