Thanks Bob, That it helps a lot I must admit I have a lot to learn about Rydberg matter. Would these highly excited and Bohr atom like elliptical orbitals still correspond to some kind of quantum mechanical orbital? Perhaps a highly excited S orbital or something? Even highly excited P, D, F and G orbitals would tend to have more complex shapes I think? I suppose it would depend on the orbitals angular momentum. I suppose we might also need to consider the spin as well as angular momentum though in the models if quantum mechanical models are used. Perhaps at these energies the Bohr Model fits better the observed behavior.
