Nuclear magnetic moments in covariant density functional theory

Abstract

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.

“…Finally, nuclear density-functional theory (DFT) has proved to perform globally well for charge radii and electric quadrupole moments of even-even nuclei across the nuclear chart [18,19]. In contrast, however, DFT calculations in open-shell odd systems still demand further developments to allow for an overall good description of electromagnetic moments [20][21][22][23][24].…”
