How accurately has the electron affinity of Hydrogen been simulated (compared to its measured value of 0.754195 eV)?

It seems like this could be a good check on whether two electrons have any ability to jointly occupy a single state (the current theory, where electrons are fermions, says that this ability is exactly zero).

  • $\begingroup$ @JonCuster That sounds like an answer. If I understand correctly, they get 0.754246 eV without even including relativistic or QED effects...really? $\endgroup$
