CLASSIFICATION OF X-RAY-SPECTRA OF 2-3 TRANSITIONS IN THE NE-LIKE AND NA-LIKE ISOELECTRONIC-SEQUENCES OF THE ELEMENTS FROM KRYPTON TO MOLYBDENUM

Plasmas produced by the laser irradiation of solid targets and in a plasma focus device have been employed as sources of X-ray spectra of the elements Kr(Z=36)-Mo(Z=42). The Ne-like isoelectronic sequence has been investigated by comparing observed wavelengths with ab initio atomic structure calculations and isoelectronic interpolation. Previous identifications in Ne-like ions have been extended to krypton, rubidium and strontium. The Na-like satellite structure of these elements has also been studied and a detailed classification of these satellites is presented.
