Title: Fe xvii X-ray Line Ratios for Accurate Astrophysical Plasma Diagnostics
Published: February 20, 2011
Abstract: New laboratory measurements of the Ne-like Fe xvii x-ray lines in the 15-17 Angstrom range are presented, along with new theoretical predictions. These results establish consistency between independent laboratories and opens the door to trustworthy application of these lines for astrophysical diagnostics. Various factors which can modify the interpretation of the raw data for accurate diagnostics are summarized and discussed.
