The density, temperature, and radiation coupling are investigated in strongly radiating Ar-Ne Z -pinch plasmas at stagnation using a novel high resolution space- and time-resolving x-ray spectrometer. One- and two-dimensional electron temperature profiles are obtained from the slope of the Ne recombination continuum. The electron density and ion temperature are determined from comparisons of the heliumlike Ar Rydberg series with detailed line-profile calculations. 2D nonlocal thermodynamic equilibrium calculations predict a radiating region denser and cooler than measured. {copyright} {ital 1998} {ital The American Physical Society}
