Rydberg, type experiment

Therefore, the energy separation between 5 i and Ti is 1 eV. For Rydberg-type excitations, the separation is, as a rule, 0.1 eV for valence-type excitations, it is 1-2 eV [22]. The separation of 1 eV is in favor of valence excitations in agreement with the results of those quenching experiments in which the kinetic distance was found to be comparable with the molecule diameter (Sec. 3.1). 

Using an apparatus of the type shown in Fig. 7.1, Bayfield and Koch (1974) conducted an ionization experiment with hydrogen Rydberg atoms that were prepared in the band 63 < tiq < 69 and exposed to electromagnetic radiation of three different frequencies Wj = 2nfi, with fi = 30 MHz,... 

In the early 1970s, when it had been recognized that experiments of beam-foil specfroscopy could produce lifetimes for many types of atomic transitions, we carried out a number of computations and analyses of transifion probabilities in atoms, with and without heavy valence-Rydberg state mixing. As we wrote in Ref. [26b], fhaf work revealed that (non int) corresponds to correlation vectors with small coefficients which are reasonably well decoupled from T and (int). This implies A) Their direct contribution to (, D /) is very small. I.e., the last three terms of eq. (12) are negligible because of the small...
