Abstract：
Relativistic mean field theory in the rotating frame is used to describe superdeformed nuclei. Nuclear currents and the resulting spatial components of the vector meson fields are fully taken into account.It is shown that the filling of specific orbitals can lead to bands with deexcitation γ-ray energies differing by at most a few keV in nuclei with two mass units difference.The results is in a good agreement with the recent experimental data over a range of angular momenta.
