The method of x-ray spectroscopy is used to measure the effective charge of a plasma with n/sub e/(0) =8 x 10/sup 13/ and T/sub e/(0) =1 keV. The energies of the detected x rays lie in the range 2.5--7 keV. The value of Z/sub eff/ turns out to be 2 and is distributed uniformly over the plasma cross section. Recombination is incorporated in the calculation of Z/sub eff/. It is assumed that t the plasma is contaminated by an impurity of only a single species, oxygen or iron. The corresonding ion densities at the center of the plasma turn out to be n/sub i/=6 x 10/sup 11/ and 10/sup 11/ cm/sup -3/.
