“…Indeed, the contribution of tensor interactions to single-particle energies depends on the filling of shells. It (nearly) vanishes in spin-saturated nuclei, whereas it might be significant when only one out of two spin-orbit partner levels is filled for one or even both nucleon species [1].…”

This article extends previous studies on the effect of tensor terms in the Skyrme energy density functional by breaking of time-reversal invariance. We have systematically probed the impact of tensor terms on properties of superdeformed rotational bands calculated within the cranked HartreeFock-Bogoliubov approach for different parameterizations covering a wide range of values for the isoscalar and isovector tensor coupling constants. We analyze in detail the contribution of the tensor terms to the energies and dynamical moments of inertia and study their impact on quasi-particle spectra. Special attention is devoted to the time-odd tensor terms, the effect of variations of their coupling constants and finite-size instabilities.

“…As a consequence, energy gaps between single-particle orbitals can be reduced and new shell gaps may appear, altering the magic numbers that were first explained by Goeppert-Mayer in 1948 [1]. The interplay among central, spin-orbit, and tensor components of the effective nucleon-nucleon interaction can shift effective single-particle energies relative to each other as protons and neutrons fill certain orbitals near the Fermi surface in nuclei with large neutron excess [2][3][4][5][6][7][8][9][10][11]. This shell evolution far from stability has been experimentally observed in different mass regions: The magic numbers at N = 20 and 28 disappear for very proton deficient nuclei, and new magic numbers at N = 14, 16, 32, and 34 seem to appear [12][13][14][15][16][17][18][18][19][20][21][22][23].…”

“…Shell-model calculations predict changes in the shell structure also for exotic nuclei near the Z = 28 and N = 40 and 50 shell closures [4][5][6][24][25][26]. The evolution of proton singleparticle states as a function of neutron number for the chain of Ni isotopes between 68 Ni and 78 Ni was investigated using the GXPF1 residual interaction [4,5].…”

The level structure of the neutron-rich 69 Cu, 71 Cu, and 73 Cu isotopes has been investigated by means of multinucleon transfer reactions. The experiment was performed at Laboratori Nazionali di Legnaro using the AGATA Demonstrator array coupled to the PRISMA magnetic spectrometer. Lifetimes of excited states in Cu nuclei were measured with the recoil-distance Doppler-shift method. The resulting electromagnetic matrix elements for transitions from excited states in 69,71,73 Cu nuclei are used to assess the collective or single-particle character of these states. The results are compared with predictions of large-scale shell-model calculations, giving further insight into the evolution of the proton pf shell as neutrons fill the 1g 9/2 orbital.

Novel halos in light kaonic nuclei as an indicator of nuclear equation of state at supra-normal densities

The sensitive correlations between the low-density halo structure and the high-density properties of the nuclear equation of state (EOS) are constructed in light kaonic nuclei with the relativistic mean-field theory. More specifically, the 1p 1/2 halo spreads out linearly with increasing the pressure and sound velocity square at supra-normal densities and decreasing the incompressibility at saturation density. These results suggest that the novel halo in light kaonic nuclei can serve as a sensitive indicator of the nuclear EOS of symmetric matter at supra-normal densities. The experimental production and detection of the light kaonic nuclei, yet to be available, is discussed in some details at last.
