Encouraged by our previous theoretical results that indicated the stabilization of the HeO unit inside the ferroelectric cavity composed of two parallel LiF dipoles, we have now undertaken the theoretical study for the related noble gas systems, (NgO)(MF)2, Ng = Ar, Kr, Xe, M = Li, Na, K. The computational results indicate that all such molecules constitute local minima, which are protected by ...

The release properties of a UCx thick target associated with a hot plasma ion source have been studied. Measurements have been performed for various elements: Kr, Ag, Sn, I and Xe. The analysis is made assuming pure diffusion or pure effusion as the release processes. The results obtained are compared to the data available in the literature. 2006 Elsevier B.V.

Significant fractionation of dust/gas from the original interstellar doud during the formation of the solar system is a distinct posfilbility. Identification of such an effect would provide important clues to nebular processes. Fractionation of volatiles is not constrained by CI abundances and only for the most abundant ones by photospheric observations. The solar Xe elemental abundance is dete...

A bstract Double electron capture by proton-rich nuclei is a second-order nuclear process analogous to double beta decay. Despite their similarities, the decay signature quite different, potentially providing new channel measure hypothesized neutrinoless mode of these decays. The Standard-Model-allowed two-neutrino (2 νEC EC ) has been predicted for number isotopes, but only observed in 78 Kr, ...

The vibrational properties (phonons) of a one-dimensional periodic phase of atoms physisorbed in the external groove of the carbon nanotube bundle are studied. Analytical expressions for the phonon dispersion relations are derived. The derived expressions are applied to Xe, Kr and Ar adsorbates. The specific heat pertaining to dense phases of these adsorbates is calculated. PACS numbers: 65.80....

Data from the mass spectrometer on the Galileo Probe indicate an approximately uniform enrichment (relative to hydrogen) of 3±1 times the solar value for Ar, Kr, Xe, C, S and N on Jupiter. These data also reveal that 15N/14N = 2.3 ± 0.3 × 10−3 in Jupiter’s nitrogen, indicating that this element reached the planet primarily in the form of N2 . These two findings strongly suggest that a disk inst...

Efficient adsorption and segregation of Xe & Kr gases is high importance in commercial as well nuclear industries. Systematic ab initio calculations reveal that transition metal (TM) decorated boron doped graphene (BDG-TM) sheet can act an efficient substrate for adsorptive capture (adatoms). Substantial enhancement the energy (E_ads) obtained on BDG-TM substrates it varies BDG-Cu > BDG-Ni BDG-...
