A study of ultra-low energy electron - hydrogen fluoride scattering using high-n Rydberg atoms: Possible role of dipole-supported states
(1996)
A detailed experimental and theoretical study of the interaction of very-low-energy electrons with the polar target HF is presented. This interaction is investigated experimentally by measuring rate constants for ionization ...
Investigation of the velocity dependence of free ion production in Rydberg atom collision processes
(1991)
Experiments to verify a semiclassical model of Rydberg atom collision processes revealed discrepancies between the model predictions and experimental results for the reaction$$\rm K\sp{**}(np)+SF\sb6\to K\sp{+}+SF\sbsp{6}{-*}$$at ...
Chaotic ionization of a Rydberg atom subjected to alternating kicks
(2012)
Quasi-one-dimensional Rydberg atoms exposed to alternating positive and negative electric field pulses (kicks) are an example of a chaotic atomic system. Chaotic ionization is predicted in this system via a phase space ...
Creating Strontium Rydberg Atoms
(2013-05-28)
Dipole-dipole interactions, the strongest, longest-range interactions possible between two neutral atoms, cannot be better manifested anywhere else than in a Rydberg atomic system. Rydberg atoms, having high principal ...
Determination of transient negative ion lifetimes using Rydberg atoms
(1996)
Potassium Rydberg atoms are used to investigate the lifetimes, on a picosecond timescale, of transient negative ions formed during dissociative electron attachment to CCl$\sb4$ and CF$\sb3$I. The transient negative ions ...
The kicked atom: Characterization of quasi-one-dimensional Rydberg atoms and their nonlinear dynamics
(2005)
The characteristics of strongly-polarized quasi-one-dimensional (quasi-1D) Rydberg atoms produced by photoexcitation of selected Stark states in the n = 350 Stark manifold are investigated by studying their ionization ...
Thermal energy collisions of potassium(nd) Rydberg atoms with electron-attaching molecules at intermediate n
(1990)
Thermal energy collisions of K(nd) Rydberg atoms with electron attaching molecules which result in reactions of the following types K(nd) + SF$\sb6$ $\to$ K$\sp+$ + SF$\sb6\sp-$ K(nd) + CF$\sb3$I $\to$ K$\sp+$ + I$\sp-$ + ...
Associative ionization in collisions of potassium Rydberg atoms with molecules
(1988)
The formation of long-lived ($\tau$ $\gg$ 10 $\mu$sec) product ions through associative ionization reactions of the type: K(nd) + BC $\to$ (KBC)$\sp+$ + e$\sp-$ has been investigated for 8 $\leq$ n $\leq$ 18, using a variety ...
Electron transfer in K(nd) collisions with attaching molecules at low-to-intermediate n
(1990)
Negative ion formation via electron transfer in thermal energy collisions between K(nd) Rydberg atoms and simple polyatomic molecules is studied at low-to-intermediate values of principal quantum number, n (n $<$ 40). At ...
Use of Rydberg atoms as a microscale laboratory to probe low-energy electron-molecule interactions
(2001)
Dissociative and non-dissociative electron attachment processes are investigated via electron transfer in collisions between velocity selected Rydberg atoms and molecules. Low-energy dissociative electron attachment to ...
