The distortion of resonance line shapes due to the accumulation of a large number of satellite transitions is discovered by means of X-ray optical methods with simultaneous high spectral and spatial resolution Disappearance of the resonance line emission near the target surface is observed while Rydberg satellite intensity accumulates near the resonance line position. and resonance line shapes are also shown to be seriously affected by opacity, higher-order line emissions from autoionizing states and inhomogeneous spatial emission. Opposite to resonance line emissions the satellites originate only from a very narrow spatial interval. New temperature and density diagnostics employing the 1s2131′ and 1s3131′-satellites are developed. Moreover, even-J components of the satellite line emissions were resolved in the present high resolution experiments. Line transitions from the autoionizing states 1s2131′ are therefore also proposed for space resolved Stark broadening analysis and local high density probing. Theorists are encouraged to provide accurate Stark broadening data for the transitions
