Abstract: | We analysed the emission spectra of solar prominences using the complete linearization method 5] and found simultaneously the optical depth at the line centre τ0, the doppler width of the line ΔλD and the damping width a. The results show 1) that the complete linearization method has a larger radius of convergence, 2) that we must consider the variation of the source function with depth, when determining τ0, and 3) that the calculated values of the damping constant for the H , Hβ of hydrogen and H and K lines of Calcium are all much greater than the theoretical values from doppler broadening and radiation damping, showing that other mechanisms besides these two also contribute to the broadening of prominence lines. |
