The dynamics of the implosion of a deuterium-filled microsphere has been investigated via the detailed analysis of the Ar 1s(2)-1s3p(1)P line shape. Ar is doped into the deuterium core for diagnostic purposes. For the analysis calculations of Ar 1-3 line shape including lithium-like dielectronic satellites were compared with time-resolved data. Three fitting parameters were used: (a) electron temperature, (b) electron density, and (c) relative shift of the wavelength axis between calculation and data, The temporal evolution of the core electron temperature and density were derived, and the shot-to-shot formation of the core plasma was shown to be reliable and reproducible. We report on the wavelength shift of the Ar 1s(2)-1s3p(1)P line shape between electron densities of 10(23)-10(24) cm(-3), results indicate a systematic red shift with increasing density.
