Abstract

Self-consistent Joint description of free and weakly bound electron states in plasmas is considered. Existence of two problems is emphasized: restriction of the number of atomic excited states and description of the smooth crossover from bound pair electron-ion excited states to collective excitations of tree electrons. The spectrum domain intermediate between low-lying excited atoms and free electron continuous energy levels is Studied. Density and nonideality effects arc separated. The density effects are predominant for the shape of the curve of the energy spectrum near the ionization limit. It corresponds to the Suppression of spectral lines in ideal multi-charge plasma of warm dense matter. A Suppression of collisional recombination turns Out to be a nonideality effects. The suppression agrees with the measurements for ultracold plasmas and Warm dense matter. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA. Weinehim
