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$\sp-$ + ...
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 ...
The use of K(nd) Rydberg atoms to investigate low-energy electron-molecule interactions
(1987)
Negative ion formation through electron transfer in collisions between K(nd) Rydberg atoms (10 $\leq$ n $\leq$ 110) and C$\sb7$F$\sb{14}$ and 1,1,1-C$\sb2$Cl$\sb3$F$\sb3$ is studied and provides a novel means to explore ...
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 ...
Effects of stray fields on ionization of Rydberg atoms near gold surfaces
(2010)
The present work has explained a long-standing discrepency between theory and experiment: the broadening of the distances at which Rydberg atoms ionize over a metallic surface. The uneven surface potential distribution on ...
Dynamics of Rydberg electron transfer to acetonitrile: Velocity-dependent studies
(2005)
Collisions between atoms in high Rydberg states and polar targets can lead to the formation of dipole-bound negative ions. We examine the dynamics of CH3CN- ion production through electron transfer in K(np)/CH3CN collisions ...
The use of spin-labelling techniques in the study of Penning ionization reaction dynamics
(1992)
The use of spin-labelling to study the dynamics of He (2 $\sp3$S) metastable atom ionization of atoms and simple molecules is described. Briefly, He (2 $\sp3$S) atoms created by a microwave discharge are spin-polarized in ...
The effect of internal energy on the lifetime of sulfur hexafluoride negative ions
(2007)
The lifetimes of SF-6 ions produced in K(np)/SF6 collisions at high n are being investigated as a function of target temperature over the range 300K to 600K. At room temperature collisions are found to lead predominantly ...
Design and testing of compact Mott polarimeters for use in energy- and angle-resolved polarization measurements
(1988)
UHV-compatible Mott polarimeters that employ electron accelerating voltages of $\sim$20kV have been designed and tested. The efficiency of the polarimeters, $\sim$3 $\times$ 10$\sp{-5}$, is competitive with those provided ...
