The He-like spectrum of 1s2 - 1snp transitions and satellites in Ar16+ have been measured from the plasma of the Alcator C tokamak. In the wavelength region of λ = 3.0 to 3.4 A, three groups of satellite lines 1s22σ - 1s2σ nl are observed which accompany each of the resonance lines emanating from the upper orbitals from n = 4 to n = 10. Results of new calculations are presented and used for identification of the observed spectra and for discussion of line intensities and wavelengths. All satellite lines belonging to the high n states observed (n = 4 to n = 10) have been identified in the calculations.
