Spectra of Multiply-Charged Lithium-Like Ions in a High-Temperature Plasma

Radiative-collisional model is used to investigate the kinetics excitation of levels 1s2nl, n ≤ 4 for the Li-like ions in a high-temperature plasma. It has been shown, that calculated relative line-intensities for ions from Ca XVIII to Br XXXIII enables one adequately to describe both laboratory and astrophysical plasmas. The calculated dependences of relative line-intensities on electron density were used for the diagnostics of plasma, as well as for identification of spectral lines of Li-like ions.
