The structure of hydrogenlike ions subject to an ultrastrong pulsar magnetic field is discussed. The finite-difference technique is applied in the context of perturbation theory to calculate the energy levels of the ground and several excited states of the hydrogen atom in fields of strength 2.35 x 10/sup 9/--4.7 x 10/sup 12/ gauss. The energies of levels between which electric-dipole transitions should be most likely to occur are calculated for the hydrogenlike ions He II, C VI, N VII, O VIII, Ne X, Mg XII, Si XIV, S XVI, Ca XX, Fe XXVI. These transitions would produce L..cap alpha.. photons if a magnetic field were absent. X-ray pulsars with B = 10/sup 11/--10/sup 13/ gauss might have emission lines in the 0.1--21 keV energy range representing these transitions.
