Abstract
Visible transitions of highly charged tungsten Wq+ have been observed with a compact electron beam ion trap for the charge-state range of q = 8 - 28 and the wavelength range of 365 - 475 nm. More than a hundred previously-unreported lines are presented, and the charge state of the ions emitting the lines is identified from the electron energy dependence of the spectra.
Keywords
tungsten ion, visible spectrum, electron beam ion trap
