We report experiments in which positronium (Ps) atoms, optically excited to Rydberg states with principal quantum numbers n in the range 18-25, were selectively ionized by both static and pulsed electric fields. The experiments were modeled using Monte Carlo simulations that include tunnel ionization rates calculated for hydrogen and scaled by the Ps reduced mass. Our measurements exhibit a small disagreement with the calculated tunnel ionization rates. Despite this we show that the electric fields in which different Ps states are ionized are sufficiently separated to allow selective field-ionization methods to be used in typical experimental conditions.

“…This method is based on the formalism of nonlinear dynamic resonances and the evolution of dynamic chaos in Hamiltonian Figure 13. Temporal evolution of binding energy ε of the 13P-state (l = 1) of the Rydberg electron in the Sommerfeld atom in an external microwave field of frequency ω = 1/13 3 and amplitude E 0 = 10E c , which exceeds ten times the critical value E c . The calculations were performed for three values of Sommerfeld parameter: α = 0, 2.81, and 4.5.…”

“…The interest in the research of physical processes involving highly excited (Rydberg) atomic systems is caused by their significance in the fundamental issues of science (due to the combination of quantum and classical properties) [1,2] and the prospects of their wide implementations in modern applied knowledge-intensive technologies (see, e.g., [3]). The main feature of Rydberg particles is their extremely big size~n 2 (where n is the principal quantum number), which results in huge dipole moments.…”

Atoms and molecules in highly excited (Rydberg) states have a number of unique characteristics due to the strong dependence of their properties on the values of principal quantum numbers. The paper discusses the results of an investigation of collisional Rydberg complexes specific features, resulting in the development of dynamic chaos and the accompanying diffusion autoionization processes. It is shown (experiment and theory) that, in subthermal low energies, the global chaotic regime that evolved in quasimolecular systems leads to significant changes in the Rydberg gases radiation/ionization kinetics. The effect of Förster resonance on the width of the fluorescence spectra and stochastic ionization processes in Rydberg systems is also discussed.

“…Diverse and quite advanced is the theme of cold collisions in cooled and trapped samples of atoms, often alkali atoms, (also of cold atoms excited to Rydberg states [8,9]) at temperatures T < 1 mK, often classified as "ultracold" temperatures, as e.g., in Ref. [10]).…”
