Experimental Stark Widths and Shifts for Spectral Lines of Neutral and Ionized Atoms (A Critical Review of Selected Data for the Period 2001 through 2007)

摘要

A critical review of the available experimental data on Stark widths and shifts for spectral lines of non-hydrogenic neutral atoms and positive ions has been carried out. The review covers the period from 2001 through theend of 2007 and represents a continuation of earlier critical reviews up to 2000. Data tables containing the selectedexperimental Stark broadening parameters are presented with estimated accuracy. Guidelines for the accuracyestimates, developed during the previous reviews, are summarized again. The data are arranged according toelements and spectra, and these are presented in alphabetical and numerical order, respectively. A total of 41 spectraare covered. Comparisons with comprehensive calculations based on semi-classical theory or on semi-empiricalmethod are made whenever possible, since the comparison with theory has often been a principal motivation for theexperiments. The 2008 edition of "A Critical Review of Selected Data" continues the material already published in theJournal of Physical and Chemical Reference Data in 2002'. The data collected for the period from 2001 through endof 2007, has been evaluated and included in the present edition. The source of literature references has been the Atomic Spectral Line Broadening Bibliographic Database'and the data bases "BiblioPl@netS ERLWebspir 5" of "I'Institut de l'Information Scientifique et Technique"(INIST). This tabulation is a continuation of a series of critical reviews and tables on experimental Stark broadeningdata for spectral lines of non-hydrogenic atoms and ions which started in 1976~(3,4) and continued in 19845~(5,6), 1990~7and2002~1 Generally, we have adhered to the format of the previous reviews, and we have subjected the data again to thesame evaluation criteria as established earlier. Our main source of literature references has been the master file of the Data Center on Atomic Line Shapesand Shifts at the National Institute of Standards and Technology (formerly the National Bureau of Standards), the"Bibliography on Atomic Line Shapes and Shifts' and the Digital Library for Physics and Astronomy' (ADS).That issue of the critical review has been accepted in "New Astronomy Review". Improvements in the experimentalmethods will be underlined in the present contribution, as the astrophysical interest~(10,11)of such Stark parametersmeasurements.
