Although based on lectures given for graduate students and postgraduates starting in
plasma physics, this concise introduction to the fundamental processes and tools is as well …

Multiply charged ions of iron dominate the EUV spectrum of the solar corona. For the
interpretation of such spectra, data on both the atomic structure and the transition rate are …

The Fe IX spectrum features two lines in the extreme ultraviolet whose ratio has been rated
among the best density diagnostics in the solar spectrum. One line is an E 1-allowed …

We present the details of an accurate lifetime measurement of the 1 s 2 2 s 2 2 p P 3∕ 2 o 2
metastable level in boronlike Ar xiv performed at the Heidelberg electron beam ion trap [A …

The lifetime of the 3 s 2 3 p P 3∕ 2 o 2 first excited energy level of Fe XIV (Al like) was
measured at the Heidelberg electron beam ion trap by monitoring its optical decay to the …

We have used an electron beam ion trap to measure electron-density-diagnostic line-
intensity ratios for extreme ultraviolet lines from Fe xii, xiii, and xiv at wavelengths of≈ 185 …

Atomic lifetime measurements span a wide range, from attoseconds to years. The frontier of
exploratory lifetime measurements, presently, is in the long part of the above time range …

The magnetic dipole (M 1) line strength between the fine-structure levels of the ground
configurations in B-, F-, Al-, and Cl-like ions are calculated for the four elements argon, iron …

Accurate atomic lifetime data are useful for terrestrial and astrophysical plasma diagnostics.
At accuracies higher than those required for these applications, lifetime measurements test …

We present an experimental observation of the visible magnetic dipole transition between
the fine structure levels in the ground term of Ba 6+(5 s 2 5 p 2: P 0 3− P 1 3) with a compact …
