Abstract

The fluorescence of dense rare gas targets has been produced and analyzed using X-ray flash, e-beam and ion beam as excitation techniques. For the first time to our knowledge an extended database of argon and krypton molecular UV emissions, i.e. the Molecular Ion Continua, has been obtained with a very good agreement between spectra whatever the pumping technics is used. The estimation of potential surface for both singly and doubly charged argon trimers and the consideration of previous ab initio calculation for the argon dimer enables us to confirm some former hypothesis but also to suggest new pathways likely to be at the origin of the population of the upper states radiating in the Molecular Ion Continua.
