Abstract
We present a method for estimating line broadening in the framework of a general average-atom model. This method is an extension of our previous work [Phys. Rev. A 29, 2789 (1984)]. It can reproduce the overall shapes of the ‘‘hilly features’’ present in spectra of hot dense plasmas in local thermodynamic equilibrium. Calculations are presented for a hafnium plasma, and the results are compared with experimental ones.Keywords
