Ion properties from high-L Rydberg atom spectroscopy : applications to nickel
An effective potential model describing high-L Rydberg states was systematically derived. The model assumes that the response of the core ion to the electric field of the Rydberg electron is at least approximately adiabatic; in other words, the excitation energies of the core ion are large compared to the typical energies of the Rydberg levels. The resulting model should describe a wide variety of high-L Rydberg systems. It can be used, in combination with experimental measurements of fine structure patterns, to extract measurements of core ion properties that control long-range interactions ...
