“…During the past two decades, it has received wide attention due to its success in describing many nuclear phenomena for the stable nuclei [2,3] as well as nuclei even far from stability [4,5]. It has been shown that the relativistic Brueckner theory can reproduce better the nuclear saturation properties (the Coester line) in nuclear matter [6], present a new explanation for the identical bands in superdeformed nuclei [7] and the neutron halo [8], predict a new phenomenon -giant neutron halos in heavy nuclei close to the neutron drip line [9], give naturally the spin-orbit potential, the origin of the pseudospin symmetry [10,11] as a relativistic symmetry [12,13,14] and spin symmetry in the anti-nucleon spectrum [15], and present good description for the magnetic rotation [16] and the collective multipole excitations [17], etc.…”

A Shell-model-Like APproach (SLAP) suggested to treat the pairing correlations in relativistic mean field theory is introduced, in which the occupancies thus obtained having been iterated back into the densities. The formalism and numerical techniques are given in detail. As examples, the ground state properties and low-lying excited states for Ne isotopes are studied. The results thus obtained are compared with the data available. The binding energies, the odd-even staggering, as well as the tendency for the change of the shapes in Ne isotopes are correctly reproduced.

“…In other words, the time-odd fields will have the same effect as the "back-flow" effect or the RPA type summation of p-h and p-n bubbles and give rise to the core polarization which will modify the nuclear current, single-particle spin and angular momentum, giving the appropriate magnetic moments. In fact, the time-odd fields are very important for the description of the magnetic moments [9,33], and rotating nuclei [34,35], etc.…”

Time-odd triaxial relativistic mean field approach for nuclear magnetic moments

2006

The time-odd triaxial relativistic mean field approach is developed and applied to the investigation of the ground-state properties of light odd-mass nuclei near the double-closed shells. The nuclear magnetic moments including the isoscalar and isovector ones are calculated and good agreement with Schmidt values is obtained. Taking 17 F as an example, the splitting of the single particle levels ( around 0.7 MeV near the Fermi level ), the nuclear current, the core polarizations, and the nuclear magnetic potential, i.e., the spatial part of the vector potential, due to the violation of the time reversal invariance are investigated in detail.

“…The measurements of absolute electromagnetic transition rates for excited states in the yrast band structure performed in this work hence provide further opportunities to test the model predictions. We also extend the theoretical investigations to tilted axis cranking relativistic mean-field theory (TAC-RMF) [35] in order to assess the possibility of magnetic rotation as an alternative scenario for explaining the observed band structures (see below).…”

Lifetimes of excited states in the neutron-deficient odd-odd nucleus 166 Re have been measured for the first time using the recoil distance Doppler-shift method. The measured lifetime for the (8 − ) state; τ = 480 (80) ps, enabled an assessment of the multipolarities of the γ rays depopulating this state. Information on electromagnetic transition strengths were deduced for the γ -ray transitions from the (9 − ), (10 − ), and (11 − ) states, and in the case of the (10 − ) and (11 − ) states limits on the B(M1) and B(E2) strengths were estimated. The results are compared with total Routhian surface predictions and semiclassical calculations. Tilted-axis cranking calculations based on a relativistic mean-field approach (TAC-RMF) have also been performed in order to test the possibility of magnetic rotation in the 166 Re nucleus. While the TAC-RMF calculations predict a quadrupole-deformed nuclear shape with similar β 2 deformation as obtained by using the TRS model, it was found that the experimental electromagnetic transition rates are in better agreement with a collective-rotational description.
