Based on the calculated wavelengths and transition probabilities of n-3 to n-2 transitions for Ne-like, Na-like, Mg-like and Al-like ions of La, in the case of high temperature condition and local thermodynamic equilibrium approximation, we simulated the spectral structure of all the charged states by considering the broadening of individual line and overlapping of a large number of lines in plasma, presented the mean wavelengths and half width of the satellite peaks, interpreted the previous experimental spectral structures, and predicted some new satellite peaks in a larger wavelength region.
