Lithium-like carbon lines have been analyzed to obtain the electron density and temperature of the emissive plasma region in the tokamak divertor, where high electron density up to have been deduced near the X-point region for detached plasmas. To confirm the measured electron density, we propose to use line broadening. In this paper, profiles of C IV n=5-6 ( = 465.8 nm) and n=6-7 (= 772.6 nm) lines are computed for plasma conditions of tokamak divertors (, =1-10 eV). The first comparisons are promising and encourage fitting of various experimental data from JT-60U and other magnetic fusion devices. Our results are based on calculations made with a modified version of the PPP line shape code using an atomic data basis built with the most accurate available data for carbon in addition to the Cowan code.
