Extended Data Table 2 Details of the theoretical contributions for the He-like U transition

From: Testing quantum electrodynamics in extreme fields using helium-like uranium

  1. Main theoretical contributions to the 1s1/22p3/2 J = 2 → 1s1/22s1/2 J = 1 intrashell transition energy in He-like uranium12. All values are in eV. See also Table 1 and Fig. 3.
  2. aUncertainty due to the finite nuclear size of the nucleus.
