Fig. 3. Comparison of the line width (HWHM) per perturber with temperature computed in this work for the dominating 2p-3d component of H (lower full) and 2p-4d component of H (upper full) with that of the resonance broadening theory of Ali & Griem (dashed) for the 2p state, and our calculation of the resonance broadening (dot-dash) for this state.
