Most vacuum devices are hampered by ion bombardment due to residual gases. Sometimes, it causes the breakdown of devices and shortens their life. In this article, the effect of the ion bombardment on the cathode surface in a structure of a field emission display was simulated. In this structure, a special type of spacer was used, named “hop” and “flu” spacer. The trajectories of electrons emitt...

In the elastic differential cross-section of the N+-rare gas systems two different types of oscillations have been observed. At an energy of a few eV a primary rainbow was detected for all systems. In the case of N+ —Ar, secondary rainbows were resolved too. From these experimental data the potential depths were determined to be : e (N+ — Ne) = 0.4 eV, s (N + — Kr) = 0.29 eV, f ( N + — Xe) = 0....

Introduction:Most of the primordial noble gases in meteorites are trapped in a poorly characterized carbonaceous carrier named " phase Q ". Marrocchi et al. [1] reported that the HF/HCl residue of Orgueil (CI) lost the low temperature fractions of heavy noble gases (36 Ar, 84 Kr and 132 Xe) in phase Q upon pyri-dine treatment. As pyridine is known to induce the swelling of the macromolecular ne...

We review the influence of rare-gas layers on image-potential states at metal surfaces. Experiments on Xe, Kr, and Ar on Cu(100) and on Xe/Ru(0001) that use the technique of time-resolved two-photon photoemission are discussed. The energetic position of the electron affinity, the geometry of the adsorbate layer, and dielectric screening are the factors that influence the dynamical and energetic...

Photoionization of He droplets doped with rare gas atoms (Rg=Ne, Ar, Kr, and Xe) was studied by time-of-flight mass spectrometry, utilizing synchrotron radiation from the Advanced Light Source from 10 to 30 eV. High resolution mass spectra were obtained at selected photon energies, and photoion yield curves were measured for several ion masses (or ranges of ion masses) over a wide range of phot...

Studies of the growth-modifying actions for Escherichia coli, Saccharomyces cerevisiae, and Tetrahymena thermophila of helium, nitrogen, argon, krypton, xenon, and nitrous oxide led to the conclusion that there are two definable classes of gases. Class 1 gases, including He, N(2), and Ar, are not growth inhibitors; in fact, they can reverse the growth inhibitory action of hydrostatic pressures....

The strength distributions, including giant resonances, of isovector and isoscalar spin-multipole transitions in the commonly studied double-$\ensuremath{\beta}$-decay triplets are computed framework quasiparticle random-phase approximation (QRPA) using Bonn-$A$ two-body interaction no-core single-particle valence spaces. nuclei include double-$\ensuremath{\beta}$ parent daughter pairs ($^{76}\...

Actually, there is a growing interest in chemical reactions involving noble gases. The experimental evidence of molecules like HArF promoted a renewed interest on the noble gas research field [1-2]. However, some aspects are still unknown [2]. One of them is the importance of relativistic effects in reaction mechanism calculations by quantum chemistry methods. Decomposition pathways for HArF an...
