R-matrix calculations along sequences: photoionization and electron-impact excitation
- NASA Goddard Space Flight Center, Code 662, Greenbelt, MD 20771 (United States)
As computer power continues to increase, so does our ability to carry out extensive, non-perturbative calculations of atomic processes. Much work has been done on increasing the target representation of complex systems in step with advances in computational power. However there is also a need for coverage in terms of atomic data used in astrophysical or fusion plasma modeling. In this talk, we discuss recent R-matrix calculations of electron-impact excitation and photoionization over iso-electronic sequences. While automation of R-matrix codes and data analysis are reviewed, the talk is focused on iso-electronic trends observed in the data. Specifically, we show the effect that resonant enhancement and level mixing can have on expected iso-electronic trends.
