The Rydberg states of an atom or molecule are electronically excited states with energies that follow the Rydberg formula as they converge on an ionic state with an ionization energy. Although the Rydberg formula was developed to describe atomic energy levels, it has been used to describe many other systems that have electronic structure roughly similar to atomic hydrogen. In general, at sufficiently high principal quantum numbers, an excited electron-ionic core system will have th… WebRydberg atoms are highly excited atomic levels for which the electron is far away from the nucleus and thus only see the 1/r potential Coulomb potential of the atomic core. In our experiment, the atom is initially prepared in a …
