Energy Levels and Observed Spectral Lines of Xenon, Xe I through Xe LIV

The energy levels and observed spectral lines of the xenon atom, in all stages of ionization for which experimental data are available, have been compiled. Sufficient data were found to generate level and line tables for Xe I–Xe XI, Xe XIX, Xe XXV–Xe XXIX, Xe XLIII–Xe XLV, and Xe LI–Xe LIV. For Xe LIII and Xe LIV theoretical values are compiled for the energy levels. In 15 of the other stages a few lines are reported. Experimental g factors are included for Xe I, Xe II, and Xe III. A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.

Energy Levels and Observed Spectral Lines of Ionized Argon, Ar II through Ar XVIII

The energy levels and observed spectral lines of ionized argon atoms, in all stages of ionization, have been compiled. Sufficient experimental data were found to generate level and line tables for Ar II through Ar XV . For Ar XVI a mix of experimental and theoretical data were used. Because of the superiority of the theoretical data for Ar XVII and Ar XVIII , theoretical values are compiled for the energy levels and the lines are calculated from them. Experimental g-factors are included for Ar II . A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.

Energy Levels and Observed Spectral Lines of Krypton, Kr I through Kr XXXVI

The energy levels and observed spectral lines of the krypton atom, in all stages of ionization for which experimental data are available, have been compiled. Sufficient data were found to generate level and line tables for Kr I–Kr X and Kr XVIII–Kr XXXVI. For Kr XXXV and Kr XXXVI and most of Kr XXXIV theoretical values are compiled for the energy levels. In all of the other stages a few lines, some of which may be only tentative classifications, are reported. In addition for Kr I, separate tables of energy levels are tabulated for the isotopes 86Kr and 84Kr. Experimental g factors are included for Kr I and Kr II. A value, either experimental, semiempirical, or theoretical, is included for the ionization energy of each ion.

A resonance ionization spectroscopy/resonance ionization mass spectrometry data service. II, Data sheets for Al, Ca, Cs, Cr, Co, Cu, Kr, Mg, Hg and Ni

Abstract A data service has been established at the National Institute of Standards and Technology to provide the necessary information to apply the techniques of Resonance Ionization Spectroscopy (RIS) and Resonance lonization Mass Spectrometry (RIMS) to routine use in analytical chemistry. This service collects and calculates the relevant atomic data, chooses appropriate resonance ionization schemes, and indicates pertinent operating details of successful RIMS studies. The first group of data sheets was published previously covering the elements As, B, Cd, C, Ge, Au, Fe, Pb, Si and Zn. The second group of data sheets is presented here. It covers the elements Al, Ca, Cs, Cr, Co, Cu, Kr, Mg, Hg and Ni. Others will be published periodically. Reprints of RIS/RIMS work are solicited so that those efforts may be included in future data sheets.

Wavelengths, Energy Level Classifications, and Energy Levels for the Spectrum of Neutral Neon

We have prepared a comprehensive critically evaluated compilation of the most accurate wavelength measurements for classified lines of neutral neon (Ne I) in its natural isotopic abundance. Data from 19 sources spanning the region 256 A to 54 931 A are included. Based on this line list we have derived optimized values for the energy levels of neutral neon. Tabular data for 1595 classified lines and 374 energy levels are provided. In addition to the observed wavelengths, we present revised wavelengths calculated from the optimized energy levels for all lines that have been previously recommended for use as secondary wavelength standards.

Interfaces in Mo/Si multilayers

Using state-of-the-art instruments and electron microscopy, the interfaces in Mo/Si multilayer mirrors fabricated by UHV electron-beam evaporation and by sputtering were examined. Peak shifts were observed in the XPS spectra at growth temperatures as low as 50 C, indicating the formation of silicide at the interface. The TEM micrographs showed that, in multilayers, the majority of the silicide formed at Mo on Si interfaces, rather than at Si on Mo interfaces. At 300 C, the multilayer structure is almost completely destroyed by the reaction. Mirrors with d(Mo) of about 40 A performed much better than those with d(Mo) of about 55 A. The Auger depth profiles showed that oxygen uptake in the sputtered samples and in samples evaporated at 200 C is limited to the top Mo layer, while samples evaporated at temperatures below 200 C had oxygen penetration through at least the first few bilayers, indicating that the silicide layers act as diffusion barriers to the oxygen.
