Heasley, J. N. ; Kneer, F. Abstract A method for treating the effects of partial frequency redistribution (PRD) in non-LTE radiative-transfer problems is presented in which the rate equations may be kept in their usual form and the PRD effects may be included by altering the form of the radiative-transfer equation. The required modifications of the transfer and statistical-equilibrium equations are outlined along with the changes these necessitate in the complete linearization method. The formulation is compared with that of Milkey et al. (1973), and sample PRD calculations are given for the solar chromospheric Ly-alpha and Ca II K line profiles. The results are found to be in excellent quantitative agreement with previous computations.
