HIGH DENSITY PLASMA EFFECTS ON ATOMIC AND IONIC SPECTRA

D. Burgess , R. M. Lee

Laser ccmpressed plasmas are sources of exceptionally intense electric and magnetic fields. Consequent perturbations of spectra are such that even for high ionization stage emitters with z > 10 only a few bound states may remain - and the physics of the plasma itself is complicated by the strong interactions amongst the constituent species and by near-degeneracy. The basic physics of such ultra-dense plasmas is contrasted with that usually assumed in longer established areas of laboratory and astrophysical plasma spectroscopy, theoretical problems in treating emitter-plasma interactions in dense plasmas are surveyed, and some examples are given of problems of current experimental and theoretical interest.
