Weak Fe XVII transitions in the coronal X-ray spectrum.
Abstract
Wavelengths and relative intensities are calculated for previously unknown higher members of all Rydberg series of Fe XVII known to be significantly radiated by coronal active regions. High-resolution coronal-active-region X-ray-spectrum measurements are analyzed to find these transitions. The measured wavelengths and intensities are given along with a revised value of the Fe XVII ionization potential. The work is compared with that of others, and a critical examination of the risk of erroneous identification in the present work is included
