One-loop self-energy using a numerical Green function
Hugo D. Nogueira, Maen Salman, Jean-Philippe Karr
We calculate the one-loop self-energy in hydrogenlike atoms using a numerical Green function obtained by solving the radial Dirac equation in an exponential basis set. The self-ene…

Photodetachment energy of negative hydrogen ions
Maen Salman, Jean-Philippe Karr
We report a high-precision calculation of the photodetachment energy of the hydrogen anion \mathrm{H}^{-}. The nonrelativistic bound-state energy is obtained using an exact three-b…
