“…We have calculated the MED values for the mirror nuclei A = 35 and A = 39 using the code ANTOINE [18] and the sdfp interaction. Shifts to the single-particle energies of protons and neutrons are induced by the electromagnetic spinorbit interaction E EMSO [19,20] and the E ll term deduced in Ref. [21].…”

High-spin states in 35 Ar and 35 Cl have been populated in the 24 Mg( 16 O, αn) and 24 Mg( 16 O, αp) reactions, respectively, at a beam energy of 70 MeV. The comparison between the level schemes of these mirror nuclei shows a striking asymmetry in the population yield of high-spin analog states of positive parity, which indicates different intensities of E1 transitions connecting positive-and negative-parity structures in both nuclei. Large energy differences are observed between analog states of negative parity with configurations of dominant pure single-particle character. This results from the comparison with large-scale shell-model calculations in the s 1/2 d 3/2 f 7/2 p 3/2 valence space. It is shown that important contributions to the energy differences arise from the multipole Coulomb and the relativistic electromagnetic spin-orbit interactions.

“…b) The electromagnetic corrections to the state energy are dominated by the spin-orbit contribution (EMSO) [10] and its MED term will be denoted with V Cls . There are also some smaller contributions as the orbit-orbit, the tensor and the proton density ones [2], which will be neglected here.…”

Experimental mirror energy differences along yrast bands of nuclei lying in the middle and the second part of 1 f 7/2 shell are compared with shell model calculations in the 1/7/2 and in the full pf configuration spaces, as well as with CSM calculations. MED plots are consistent with the description which emerges from the interpretation of SM calculations: i.e. the band crossing of the gs band with high-iC bands in A=51 mirror pairs, as well as the seniority-3 quasi band-termination at Ip=19/2~ in A=49. Rotational alignment effects are excluded, contrarily to what even recently proposed. Some inconsistencies are pointed out in the topical literature.

Coulomb energies of spherical nuclei

A phenomenological Coulomb energy equation has been derived for spherical nuclei with diffuse surfaces. Contributions from the direct and exchange Coulomb energy and from the electromagnetic spin-orbit interaction are included explicitly. The experimental Coulomb displacement energies of 42 essentially spherical nuclei with 2 2 28 have been subjected to a least-squares analysis with the shape parameters of the ground state charge distributions required to agree with those obtained from electron scattering and muon capture X-ray experiments. Agreement between the experimental and calculated energies with a standard deviation of about 20 keV is obtained if (i) the ratio between the rms radii of the neutron excess and the proton core is taken between about 1.10 and 1.15, (ii) a smoothly A-dependent correction term which varies between about +450 keV in the light nuclei and +350 keV in the heavy nuclei is introduced, and (iii) an averaged contribution from the electromagnetic spin-orbit interaction is used rather than the expected shell-mode1 contribution. Justification for this averaging may be provided by amounts of not less than 15 % of excitations into higher shellmodel orbits for all nuclei. The Coulomb displacement energies of vibrational and rotational nuclei are observed to be smaller by up to 200 keV than corresponding spherical nuclei. Neutron halos have been calculated and are found to be in very good agreement with the results of Hartree-Fock calculations, the droplet mode1 of Myers and Swiatecki and the calculations by Nolen and Schiffer using wave functions generated in a Woods-Saxon potential well. The calculated neutron halo for zo8Pb is 0.25kO.05 fm.
