Electron-impact excitation of Sc II: collision strengths and effective collision strengths for fine-structure transitions

Abstract Accurate fine-structure atomic data for the Fe-peak elements are essential for interpreting astronomical spectra. There is a severe paucity of data available for Sc ii, highlighted by the fact that no collision strengths are readily available for this ion. We present electron-impact excitat...
