Ct. Chantler et al., PROGRESS TOWARDS ABSOLUTE X-RAY SPECTROSCOPY ON THE NIST ELECTRON-BEAM ION-TRAP - CURRENT STATUS AND RESULTS, Physica scripta. T, T73, 1997, pp. 87-89
Recent observation of Hydrogen-like ions of Vanadium at the NIST Elect
ron-Beam Ion Trap and measurements of Helium-like resonance line are p
resented. One particular feature of the current series of experiments
is the possibility of absolute calibration in a near Doppler-free envi
ronment. The current approach to the possible measurement of QED effec
ts in such a system is reviewed There is great potential for precision
measurements in the near future.
