DIELECTRONIC RECOMBINATION IN THE AVERAGE-ATOM MODEL

R.M. MORE(^), G.B. ZIMMERMAN and Z. ZINAMON(~) University of California, Lawrence Livermore National Laboratory, Livermore, CA 94550, U. S. A.

flutoionization and dielectronic attachment are usually omitted from rate equations for the non-LTE

average-atom model, causing systematic errors in predicted ionization states and electronic populations for atoms in hot. dense plasmas produced by laser irradiation of solid targets. We formulate a method by which dielectronic recombination can be included in average-atom calculations without conflict with the principle of detailed balance. The essential new feature in this extended average atom model is a treatment of strong correlations of electron populations induced by the dielectronic attachment process
