An experimental effort is underway at NIST to enable tests of theory with oneelectron ions synthesized in circular Rydberg states from captured bare nuclei. Problematic effects which limit the accuracy of predicted energy levels for low-lying states are vanishingly small for high angular momentum (high-L) states; in particular, the nuclear-size correction for high-L states is completely negligible for any foreseeable improvement of measurement precision. The goal is to capture bare nuclei in an ion trap and make one-electron atoms in circular Rydberg states with dipole (E1) transitions in the optical domain accessible to a frequency comb.
