Rydberg energy

Here ERn is the energy of the Rydberg states, Er the ionization energy of the molecule, n the principal quantum number, S the quantum defect, and Ry the Rydberg constant. A measurement of the photoelectron spectrum immediately provides the Rydberg energies, because... 

One of the first properties to be explored was the sensitivity of Rydberg atoms to external electric fields, the Stark effect. While ground state atoms are nearly immune to electric fields, relatively modest electric fields not only perturb the Rydberg energy levels, but even ionize Rydberg atoms, as was shown in early... 

Ba Rydberg energy levels (—) and continua (///) obtained by adding the second valence electron to these Ba+ levels. The horizontal arrows show the possible interactions between channels associated with different ion levels. Interactions with other bound states lead to series perturbations while interactions with continua lead to autoionization. 

As shown by Berry [220], the phase shift increases by % at each shape resonance for positive energies above threshold. When the 4/ function drops into the inner well, 5/ moves to occupy the position of 4/ before collapse, 6/ moves to play the role of 5/, etc [201]. As far as QDT is concerned, p relates to the Rydberg energy formula applied in the outer well. Thus, if p = n—v is written with n obtained by node counting, there will be an error of 1, because in fact one should use p = n—l — v when the resonance drops below the bound states. Consequently, Seaton s theorem becomes...

This relationship is assumed to hold for an electron or hole in a semiconductor. Thus, the energy band is parabolic near the band edge. The shift of band gap energy (AEg) caused by confinement of the exciton in QDs with diameter R can be expressed as Eq. 1.5 where is the reduced mass of an electron-hole pair, and Ry is the Rydberg energy.
