The structure of hydrogen-like ions in the ultrastrong magnetic fields of pulsars is examined. A finite difference scheme within the framework of perturbation theory is used to calculate energy levels of the ground and several excited states of the hydrogen atom in fields of 2.35 x 10 to the 9th to 4.7 x 10 to the 12th G. The level energies of maximally probable electrical dipole transitions are calculated for He II, C VI, N VII, O VIII, Ne X, Mg XII, Si XIV, Ca XX, and Fe XXVI. It is suggested that X-ray pulsars with magnetic fields of 10 to the 11th to 10 to the 12th G may have emission lines caused by these transitions in the 0.1-21 keV energy range.
