“…New techniques of fully on-line nuclear magnetic resonance on oriented nuclei (NMR͞ON) make it possible to determine precisely ground and isomeric state magnetic dipole moments far from stability [4,5]. So far, the resonance effect was detected by a change in the angular anisotropy of gamma-ray emission.…”

The first fully on-line use of the angular distribution of beta emission in detection of NMR of nuclei oriented at low temperatures is reported. The magnetic moments of the single valence particle, intermediate mass, isotopes 67Ni(nup(-1)(1/2);1/2(-)) and 69Cu(pip(1)(3/2);3/2(-)) are measured to be +0.601(5) &mgr;(N) and +2.84(1) &mgr;(N), respectively, revealing only a small deviation from the neutron p(1/2) single-particle value in the former and a large deviation from the proton p(3/2) single-particle value in the latter. Quantitative interpretation is given in terms of core polarization and meson-exchange currents.

“…In summary, the studies on nuclear magnetic moments in CDFT has been reviewed. By considering the timeodd fields, one-pion exchange current, first-order, and second-order corrections, the magnetic moments of odd- A nuclei with LS and jj closed shell plus or minus one nucleon have been reproduced and this method should be extended to apply for more nuclei with a doubly closed shell plus or minus one nucleon such as 133 Sb [34], 67 Ni and 69 Cu [35], and 49 Sc [36]. In addition, the descriptions of the magnetic moments in deformed odd-A nuclei become possible.…”

“…Considerable efforts have been made to explain the deviations of the nuclear magnetic moments from the Schmidt values, which can be contributed from the meson exchange current (MEC, i.e., the exchange of the charged mesons) and configuration mixing (CM, or core polarization, i.e., the correlation not included in the mean field approximation) [5,[15][16][17][18]33]. Recently, by considering the configuration mixing and meson exchange current corrections, the newly measured magnetic moment of 133 Sb [34], 67 Ni and 69 Cu [35], and 49 Sc [36] have been well reproduced.…”

Nuclear magnetic moments in covariant density functional theory

2015

Nuclear magnetic moment is an important physical observable and serves as a useful tool for the stringent test of nuclear models. For the past decades, the covariant density functional theory and its extension have been proved to be successful in describing the nuclear ground-states and excited states properties. However, a long-standing problem is its failure to predict magnetic moments. This article reviews the recent progress in the description of the nuclear magnetic moments within the covariant density functional theory. In particular, the magnetic moments of spherical odd-A nuclei with doubly closed shell core plus or minus one nucleon and deformed odd-A nuclei.

“…Recent experimental results [1][2][3] on nuclei close to 132 Sn have lead to the determination of a nearly complete set of neutron and proton single-particle orbitals and to the establishment of some of their important statical and dynamical properties. In particular, the new results [2] for 133 Sb include information on energies of proton single particle states above the Z = 50, N = 82 shells as well as important knowledge about the decay properties of these states.…”

Isospin dependence of the spin-orbit splitting in nuclei

By the use of the latest experimental data on the spectra of 133 Sb and 131 Sn and on the analysis of properties of other odd nuclei adjacent to doubly magic closed shells the isospin dependence of a mean spin-orbit potential is defined. Such a dependence received the explanation in the framework of different theoretical approaches.Recent experimental results [1-3] on nuclei close to 132 Sn have lead to the determination of a nearly complete set of neutron and proton single-particle orbitals and to the establishment of some of their important statical and dynamical properties. In particular, the new results [2] for 133 Sb include information on energies of proton single particle states above the Z = 50, N = 82 shells as well as important knowledge about the decay properties of these states. In view of new data on single particle levels at 132 Sn we performed an analysis [4] of the available information on such states in strongly magical nuclides, with special attention to the magnitudes of the spin-orbit splittings and their isospin dependence. This question is important since such a dependence could be one of the factors contributing to significant structural changes in nuclides having an extreme neutron excess.In [2] the energy of the 3/2 + level in 133 Sb was measured to be 2.44 MeV. By using this value and also the previous data on the spectrum of single particle excitations in nuclei close to 132 Sn (see [1] and [5][6][7][8]) the values of spin-orbit splittings of the 2d levels both in proton and neutron systems of 132 Sn were defined. The splitting was found to be 1.48 MeV for protons and 1.65 MeV for neutrons, i.e. the neutron spin-orbit splitting is somewhat larger for neutrons than for protons. At the same time it was noted in [2] that for nuclei close to 208 Pb the situation is the opposite, in any case for the first glance. So, from the spectra of single particle levels in 209 Bi and 207 Pb it follows that the spin-orbit splitting of the proton 2f orbit is equal to 1.93 MeV, while for neutrons it is 1.77 MeV. However it follows from the experiment that the neutron 2f 7/2 state in 207 Pb is strongly fragmented. So, the conclusions of the work [2] refer only to the lowest, though the strongest component of this state. Identifying in the spirit of [9], [10] the true single particle energy of the 2f 7/2 state with the weighted average of 7/2 − energy levels, the weight being the spectroscopic factors of the (d,t) reaction on 208 Pb [11], we obtain the real excitation energy of this state equal to 2.70 MeV (instead of 2.34 MeV). This corresponds to the value of neutron spin-orbit splitting of the 2f orbit equal to 2.13 MeV, i.e. as for the 2d orbit in 132 Sn a little larger than that for protons. The above statement is fortified by the analysis of the 3p spin-orbit splitting near 208 Pb. Such a splitting is equal to 0.85 MeV for protons (taking into account the fragmentation of 3p1/2 level) while for neutrons it is 0.90 MeV, i.e. a little larger than for protons. The systematics of single particle energies ...
