Abstract
We perform quantum electrodynamic calculations of the ionization energy of the states of the He atom, including a complete evaluation of the correction. We find a large contribution from the nonradiative part of this correction, which has not been accounted for in previous investigations. The additional contribution shifts theoretical predictions for ionization energies by about 10. Despite this shift, we confirm the previously reported systematic deviations between measured experimental results and theoretical predictions for transitions involving states. The reason for these deviations remains unknown.
