Abstract

A Monte Carlo technique for modeling spectra with many resolved lines of ions in intermediate coupling was presented in the preceding paper [Phys. Rev. A 44, 5707 (1991)]. We use the same concept here with a modification for the near-LS-coupling case. Rosseland and Planck means of transition arrays of Fe v and Fe vi are evaluated. Comparison with exact computations shows much better agreement than is found using the simple unresolved-transition-array approximation.
