The knowledge of different species of noble gases emission spectra, relative with the understanding of laser emission mechanism, have been studied in La Plata since more than thirty years ago. Since 1985 a strong collaboration between the groups from La Plata and Campinas in the analysis of the ionic emission spectra of noble gases, was started
[1,2] and references therein. With the purpose of continuing this line of work we present results about neon, argon, krypton and xenon, in particular for six times ionized argon and xenon, and eight times ionized xenon. The spectra were recorded in the V.U.V. and in the UV,Visible region, and were excited by using a pulsed discharge, and a theta pinch light sources. New classified lines and energy levels were established. The results of these analysis were supported by using relativistic Hartree Fock calculations.
