Abstract
We have measured the emission lines of the heliumlike Ti x x i impurity radiation from Ohmically heated Doublet-III tokamak plasma discharges. The measured wavelengths are in good agreement with recent theoretical and experimental results. The theoretical and experimental line-intensity ratios are also in good agreement for the pure-dielectronic-recombination satellite lines. Furthermore, collisional inner-shell excitation processes are observed to contribute significantly to the q lines in tokamak plasmas.Keywords
