Magnetic rotation and antimagnetic rotation are exotic rotational phenomena observed in weakly deformed or near-spherical nuclei, which are respectively interpreted in terms of the shears mechanism and two shearslike mechanism. Since their observations, magnetic rotation and antimagnetic rotation phenomena have been mainly investigated in the framework of tilted axis cranking based on the pairing plus quadrupole model. For the last decades, the covariant density functional theory and its extension have been proved to be successful in describing series of nuclear ground-states and excited states properties, including the binding energies, radii, single-particle spectra, resonance states, halo phenomena, magnetic moments, magnetic rotation, low-lying excitations, shape phase transitions, collective rotation and vibrations, etc. This review will mainly focus on the tilted axis cranking covariant density functional theory and its application for the magnetic rotation and antimagnetic rotation phenomena.

The g-factors of Ground Rotational Band states of N = 44 isotones 82 Sr, 83 Y, 84 Zr and 85 Nb have been measured by the transient-magnetic-field ion implantation perturbed angular distribution (TMF-IMPAD) method. The measured g-factors of 82 Sr increase with the increase of spin I, indicating a proton alignment only. Positive peaks appear in the variation of g-factors with spin for 83 Y and 84 Zr at spin 21/2 + and 10 + respectively, indicating a proton alignment followed by a neutron alignment. A negative peak occurs for 85 Nb at the spin 25/2 + , indicating a neutron alignment followed by a proton alignment.

Study of dependence of quasi-particle alignment on proton and neutron numbers in A = 80 region through g-factor measurements

et al. 2010

Dependence of quasi-particle alignment on proton and neutron numbers has been studied in A = 80 mass region through g-factor measurements by using TMF-IMPAD. The experimental results show that for the nuclides 84 Zr, 85 Zr and 86 Zr with Z = 40 the proton alignment is followed by the neutron alignment in 84 Zr and 85 Zr, while the neutron alignment is followed by the proton alignment in 86 Zr, and for the nuclides 82 Sr, 83 Y, 84 Zr and 85 Nb with N = 44 the proton aligns only in 82 Sr, the proton alignment occurs first that is followed by the neutron alignment in 83 Y and 84 Zr and the neutron alignment is followed by the proton alignment in 85 Nb. Proton and/or neutron alignments lead to different patterns of the g-factor variation with spin.
