    "abstract": "Time evolution of wave packets built from the eigenstates of the Dirac\nequation for a hydrogenic system is considered. We investigate the space and\nspin motion of wave packets which, in the non-relativistic limit, are\nstationary states with a probability density distributed uniformly along the\nclassical, elliptical orbit (elliptic WP). We show that the precession of such\na WP, due to relativistic corrections to the energy eigenvalues, is strongly\ncorrelated with the spin motion. We show also that the motion is universal for\nall hydrogenic systems with an arbitrary value of the atomic number Z.",
