Nuclear magnetic moments in covariant density functional theory

Abstract

As one of the most important physics observable, nuclear magnetic moment gives rich information about the nuclear structure. This article reviews the theoretical progress in nuclear magnetic moments, and presents the descriptions within the covariant density functional theory for the magnetic moments of spherical and deformed odd $A$ nuclei. For the spherical odd $A$ nuclei, taking the magnetic moment of $LS$ closed shell nucleus plus or minus one nucleon near $^{16}$O and $^{40}$Ca as examples, the time-odd fields effects are firstly discussed. Then, taking $^{207,209}$Pb, $^{207}$Tl and $^{209}$Bi as examples, including the MEC and CP corrections, magnetic moments of $j$-$j$ closed-shell nuclei plus or minus one nucleon have been studied. For deformed odd $A$ nuclei, taking $^{33}$Mg as example, its intrinsic magnetic moment has been studied with configuration-fixed deformation constrained RMF approach with time-odd fields. Finally, the description of nuclear magnetic moments within covariant density functional theory has been prospected.
