On the spectra of highly-ionized krypton, strontium, zirconium and rhodium excited in the plasma of the TFR tokamak

Abstract

Storntium, zirconium and rhodium have been injected into TFR tokamak plasmas by using the laser blow-off technique, and their spectra recorded either photographically (Zr, 10-92 Å) or photoelectrically (all three elements, 10-330 Å). Line identifications for several isoelectronic sequences from sodium-like to gallium-like are reported. Additionally, isoelectronic regularities observed for these three elements have allowed to identify a few krypton lines left unidentified in our previous work [1].
