THE EXTENDED LAW OF CORRESPONDING - STATES AND THE INTERMOLECULAR POTENTIALS FOR Ar-Ar, Ar-Kr AND Kr-Kr
An inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. The experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced...
متن کاملCommensurate Phases of Kr Adsorbed on Single-Walled Carbon Nanotubes
In this paper, we show that Krypton atoms form a commensurate solid (CS) phase with a fractional coverage of one krypton atom per every four carbons on zigzag carbon nanotubes. This is a unique phase, different from the √ 3×√3R30◦ CS monolayer formed on graphite, which has a lower coverage of one krypton atom per every six carbons. Our prediction disagreeswith experiments that observe in nanotu...

متن کاملExciton-induced desorption and surface-type luminescence of Kr atoms from Kr-doped solid Ar
Selective exotat~on of Kr atoms at the surface of sohd Ar with synchrotron radlatton stimulates the desorptlon of excited Kr atoms (e g., Kr3P1) as well as the luminescence of Kr-type surface centers at hv = 9 998 eV (3P 1) and at hv = 9.881 eV (3P 2) The high-resolution luminescence spectra and the yield curves of the radiative decay channels have been measured. They are interpreted taking int...
متن کاملNegative-Ion Enhancements in Electron-Stimulated Desorption of CF2Cl2 Coadsorbed with Nonpolar and Polar Gases on Ru(0001)
Electron-stimulated desorption of F and Cl from submonolayer CF2Cl2-covered Ru(0001) is strongly affected by coadsorption of polar molecules (H2O and NH3) and nonpolar rare-gas atoms (Xe, Kr, and Ar). Giant anionic enhancements (up to 102-104) are observed for polar molecules, which are several orders of magnitude higher than by nonpolar atoms. The giant enhancements are attributed to enhanced ...
