AXAF Project Science:
Widths for Characteristic X-Ray Lines

------------------------------------------------------------------

David Roberts and Martin Sulkanen, AXAF Project Science
May 1997

The following table contains x-ray line energies and linewidths, including those for the elements and compounds that comprise the XSS EIPS targets. The line energies were taken from Bearden (1967). Krause and Oliver (1979) have provided semi-empirical linewidths based on the sum of the level widths involved in the particular line transitions. These estimates, however, do not include line-broadening caused by collective effects expected in the solid targets of the EIPS. Salem and Lee (1976) provided a least-squares fit to the existing linewidth data for K and L lines, for elements of even values of Z from 20 through 96, including solid-state line-broadening. Since this work there have been additional precision measurements of linewidths (many of these are for Z < 40) which we use to supplant earlier data (e.g. Parratt (1933); Allison, etc.) used in Salem and Lee's fit that may have systematic errors, or did not quote an uncertainty in their stated value. In this table we provide the precision measured values of the linewidths in the published literature. Where more than one precision measurement exists for a line, we provide the error-weighted mean of these values. Values that have no accompanying uncertainty are measured values in which no uncertainty was quoted; such values represent the only published widths for these given lines. An arithmetic mean is provided for lines with several such measurements.
