In high orbital angular momentum (ℓ ≥ 3) Rydberg states, the centrifugal barrier hinders the close approach of the Rydberg electron to the ion-core. As a result, these core-nonpenetrating Rydberg states can be well described by a simplified model in which the Rydberg electron is only weakly perturbed by the long-range electric properties (i.e., multipole moments and polarizabilities) of the ion-core. We have used a long-range model to describe the vibrational autoionization dynamics of high…

Analysis of vibrational autoionization of CaF Rydberg states.
Calculations of vibrational autoionization rates of CaF Rydberg states are reported, based on the results of a global multi-channel quantum defect theory (MQDT) fit, to characterize the physical mechanisms for the interaction between the Rydburg electron and the ion-core.
Vibrational autoionization and predissociation in high Rydberg states of nitric oxide
New results on the competition between autoionization and predissociation in the high Rydberg states of nitric oxide are presented. These results provide insight into the earlier work of Park et al.
Rotationally resolved photoelectron spectra from vibrational autoionization of individual rotational levels of the nlR (v=1, 11⩽n⩽15, 0⩽lR⩽3) Rydberg states of NO are measured by combining two-color
Theoretical study of competing photoionization and photodissociation processes in the NO molecule
The multichannel quantum defect theory of dissociative recombination is reviewed and adapted to treat simultaneous vibrational preionization and electronic predissociation in NO. The photoionization,
s and d Rydberg series of NO probed by double resonance multiphoton ionization
The s and d Rydberg states of NO with v = 0 have been observed for 6 leqslant; n* leqslant; 40 by double resonance multiphoton ionization which was three-photon resonant with the 3pπC 2∏ (v = 0)
Preparation of high orbital angular momentum Rydberg states by optical-millimeter-wave STIRAP.
This proof-of-principle demonstration transfers population to an nf Rydberg state of the calcium atom by stimulated Raman adiabatic passage, and numerical simulations reproduce the observed time and frequency dependences of the population transfer and suggest the utility of this scheme to populate high-ℓ Ryd Berg states of molecules.
Laser-induced fluorescence studies of HfF+ produced by autoionization.
It is shown empirically that 30% of the total ion yield can be created in a particular ∣J(+), M(+) state and a simplified model describing autoionization from a given Rydberg state that assumes no angular dynamics is presented.

Rotational state dependence of decay dynamics in the superexcited 7f Rydberg state (υ=1) of NO
The decay dynamics of the 7f Rydberg state (υ=1) of NO has been investigated with laser multiphoton excitation methods; not only NO+ ions generated by autoionization, but also fragment nitrogen atoms
