Time-odd components in the mean field of rotating superdeformed nuclei

Abstract

Rotation-induced time-odd components in the nuclear mean field are analyzed using the Hartree-Fock cranking approach with effective interactions SIII, SkM*, and SkP. Identical dynamical moments ${\mathcal{J}}^{(2)}$ are obtained for pairs of superdeformed bands $^{151}\mathrm{Tb}$(2)${\mathrm{\ensuremath{-}}}^{152}$Dy(1) and $^{150}\mathrm{Gd}$(2)${\mathrm{\ensuremath{-}}}^{151}$Tb(1). The corresponding relative alignments strongly depend on which time-odd mean-field terms are taken into account in the Hartree-Fock equations.
