Neon Diffusion in Silver
نویسنده
چکیده
The diffusion of Ne in Ag is investigated by bombarding Ag sheet with energetic Ne ions and observing the Ne release during constant temperature anneals; giving D=2.5 * 1.5 exp (-59.5 5 2.0 x 103 Cal/mole/ RT), for volume diffusion. The activation energy is not consistent with previous values found for other inert gases in Ag but agrees with the predictions of impurity diffusion theory for diffusion via the vacancy mechanism. None of the Ne was permanently trapped in the Ag.

Optical absorption of small copper clusters in neon: Cu(n), (n = 1-9).
We present optical absorption spectra in the UV-visible range (1.6 eV < ℏω < 5.5 eV) of mass selected neutral copper clusters Cu(n)(n = 1-9) embedded in a solid neon matrix at 7 K. The atom and the dimer have already been measured in neon matrices, while the absorption spectra for sizes between Cu(3) and Cu(9) are entirely (n = 6-9) or in great part new. They show a higher complexity and a larg...
متن کاملMatrix effects on the optical response of silver nanoclusters.
We report absorption spectra for Ag(7), Ag(9), and Ag(11) in an argon matrix grown at a temperature of 28 K and compare them with previous spectra of the same species measured in matrices of argon grown at lower temperatures as well as in neon matrices. We discuss the discrepancies in the light of the matrix crystallinity and show that this leads to an understanding of the influence of the matr...
متن کاملDiffusion of neon in white dwarf stars.
Sedimentation of the neutron rich isotope 22Ne may be an important source of gravitational energy during the cooling of white dwarf stars. This depends on the diffusion constant for 22Ne in strongly coupled plasma mixtures. We calculate self-diffusion constants D(i) from molecular dynamics simulations of carbon, oxygen, and neon mixtures. We find that D(i) in a mixture does not differ greatly f...
متن کاملInfluence of dust particles on ionization and excitation in neon dc discharge
The influence of dust particles on the concentration of metastable neon atoms and ionization was investigated using the developed drift/diffusion model for plasma of positive column of glow discharge. The detailed de-excitation in neon was considered. In addition to usual plasma losses in dusty plasmas, the quenching of metastable atoms on dust particle surface was considered. The strong influe...
متن کاملSelf Diffusion and Binary Maxwell-Stefan Diffusion in Simple Fluids with the Green-Kubo Method
Self diffusion coefficients and binary Maxwell-Stefan diffusion coefficients were determined by equilibrium molecular dynamics simulations with the Green-Kubo method. The study covers five pure fluids: neon, argon, krypton, xenon, and methane and three binary mixtures: argon+krypton, argon+xenon, and krypton+xenon. The fluids are modeled by spherical Lennard-Jones pair-potentials, with paramete...
