Positron scattering from neon and argon

The Ionization of Argon and Neon by Neutral Argon Beams.

As a result of the discovery of Kallmann and Rosent"2 that the probability of charge transfer is very great for gas ions moving in a gas of their own molecular or atomic species, the possibility of obtaining an atomic beam of high intensity is at once indicated. Since the charge transfer itself takes place without altering the translatory energy of the moving ion, the translatory energy of the ...

Prediction of the thermophysical properties of pure neon, pure argon, and the binary mixtures neon-argon and argon-krypton by Monte Carlo simulation using ab initio potentials.

Gibbs ensemble Monte Carlo simulations were used to test the ability of intermolecular pair potentials derived ab initio from quantum mechanical principles, enhanced by Axilrod-Teller triple-dipole interactions, to predict the vapor-liquid phase equilibria of pure neon, pure argon, and the binary mixtures neon-argon and argon-krypton. The interaction potentials for Ne-Ne, Ar-Ar, Kr-Kr, and Ne-A...

Relativistic approach for e+/- scattering from argon.

Triple Photoionization of Neon and Argon Near Threshold

By using a pulsed electric field, the ions created in the interaction region (between the pusher and extractor plates) are accelerated toward a Z-stack configuration of multi-channel plates. The pulsed field provides a time scale for the "start" and "stop" times of an ion. This setup is sensitive to the mass to charge ratio of the ions, as shown in typical spectra such as Figures (2) and (3). I...

Constraints on neon and argon isotopic fractionation in solar wind.

To evaluate the isotopic composition of the solar nebula from which the planets formed, the relation between isotopes measured in the solar wind and on the Sun's surface needs to be known. The Genesis Discovery mission returned independent samples of three types of solar wind produced by different solar processes that provide a check on possible isotopic variations, or fractionation, between th...
