Dielectronic Satellite Lines of L-shell Mo at LLNL EBIT

ORAL

Abstract

Dielectronic recombination, an important atomic process for astrophysical and laboratory plasmas, has been studied in detail for low-Z and recently for W ions. However, there are still many details missing for other materials including molybdenum (Mo). New calculations were done for Ne-like Mo dielectronic recombination transitions using the COWAN code, HULLAC, and the relativistic many-body perturbation theory method. The EBIT-I electron beam ion trap at Lawrence Livermore National Laboratory (LLNL) was used to benchmark the new calculations. EBIT-I was operated to create Ne-like Mo using a \textasciitilde 3 keV energy beam and then using lower energy beams (0.6 -- 1.2 keV) to account for dielectronic recombination. The new theoretical calculations were compared to Na-like Mo satellite spectra collected from LLNL EBIT-I experiments with consideration to polarization sensitivities.
