Abstract
The structure of singly ionized iron, Fe II, is quite well described by an independent particle model, with LS-coupled basis functions. Deviations from this approach appear in a theoretical calculation as mixings between different levels with the same parity and J-value. These interacting levels share each others properties, e.g. allowed decay channels.
