Measurements of excitation spectra of highly charged atoms

The excitation spectra and level lifetimes of highly charged atoms for heavier elements of Ne, S and Ar have been measured by using the beam-foil method on the heavy ion accelerator in Lanzhou. Emission spectra in the wavelength region of 25-400 Anstron was studied. On the whole, the agreement between the authors' experimental results and other experiments is fairly good
