Mobility of Xe+ in Xe–Ne and Xe–He mixtures
Journal of Physics D: Applied Physics, 2011We report on the measurement of the mobility of Xe+ in Xe–Ne and Xe–He mixtures over the density-reduced electric field strength E/N, from 6.5 to 300 Td (1 Td = 10−17 V cm2), and Xe concentrations in the range 2–50%. The measurements are carried out with a pulsed Townsend apparatus (PT).

Ultraviolet emission in Xe + Xe collisions near threshold
Chemical Physics Letters, 1979Abstract Absolute cross sections have been determined for the vacuum-ultraviolet emission of Xe + Xe collisions between 10 and 15eV. The exponential energy dependence and the low absolute cross section (10 p–5 to 10 –8 A 2 ) indicate that a direct crossing is not reached.

Characterization of imprisoned Xe resonant photons in He-Xe and Ne-Xe mixtures
Journal of Physics D: Applied Physics, 1995The Holstein's theory of the imprisonment of resonance radiation for pressure-broadened Lorentzian profiles is extended to the Xe-based binary gas mixtures which are widely employed in practical discharge devices. In the binary mixtures, collisions between radiating and buffer atoms modify the emission and absorption spectrum profiles, affecting the ...

Transition Probabilities of Xe I and Xe II
Physical Review A, 1973Absolute transition probabilities of the stronger Xe I and Xe II lines between 3800 and 8400 \AA{} are measured in emission. State variables of the shock-tube plasmas are determined by several independent methods. Accuracies for 25 neutral and 128 ionic $A$ values are estimated to be (22-50)%.

Rainbow scattering for Ar+ + Ar and Xe+ + Xe
Chemical Physics Letters, 1973Elastic differential scattering measurements have been performed on Ar+ + Ar and Xe+ + Xe. The rainbow scattering angle is found at τ = Eθ ≈ 115 eV deg for Ar+2 and τ ≈ 93 eV deg for Xe+2. These data are consistent with a potential well depth of 1.25 eV for Ar+2 and 0.97 eV for Xe+2.

Chemical Physics Letters, 1976
Abstract Photoionization mass spectrometer techniques have been employed to study the charge transfer reactions: Xe+ + O2 → O+2 + Xe and O+2 + Xe → Xe+ + O2. The results show the reaction of Xe+(2P 3 2 ) ions with O2 molecules is much more efficient than the reaction of Xe+(2P 1 2 ) ions with O2 molecules.

Photoionization of the Xe atom and Xe@C60 molecule
The European Physical Journal D, 2011Photoionization of the Xe atom and Xe@C60 molecule have been studied using the random phase approximation with exchange (RPAE) method. The Xe atom was described by relaxed orbitals including overlap integrals. The C60 fullerene has been represented by an attractive short range spherical well with potential V(r), given by V(r) = −V0 for ri < r < ro ...

Unexpected Trend in Stability of Xe–F Compounds under Pressure Driven by Xe–Xe Covalent Bonds
The Journal of Physical Chemistry Letters, 2016Xenon difluoride is the first and the most stable of hundreds of noble-gas (Ng) compounds. These compounds reveal the rich chemistry of Ng's. No stable compound that contains a Ng-Ng bond has been reported previously. Recent experiments have shown intriguing behaviors of this exemplar compound under high pressure, including increased coordination ...
