We present precise results for the binding energies and sizes of the [Formula Presented] ion moving across a strong pulsar-type magnetic field. Similarly to the previously studied case of hydrogen, the ion is strongly deformed by the action of the motion-induced Stark forces. Unlike the case of the neutral hydrogen atom whose transverse motion gives rise—for every discrete state of the nonmoving atom—to a continuum of displaced energy states with changing transverse momentum, transverse motion of the [Formula Presented] ion gives rise to a discretely spaced energy spectrum. A quantitative understanding of this problem and related opacities is central in modeling neutron star atmospheres, and should help in the interpretation of thermal emission from radio pulsars.
