Abstract
The origin of the continuum observed in laser produced plasmas and other moderately ionized plasmas of rare-earth elements have been studied in detail elsewhere [1–3]. What has not been described before is the detailed nature of the electronic structure of these ionized rare-earth elements and how sets of configurations lead to the formation of so-called ‘compound’ atomic states. This approach was recently applied to a study of the level structure of neutral cerium [5]. The character of the complex electronic structure underlying this behaviour is examined in some detail and in particular, a case study is made for a small subset of the possible transitions arising in the ion Sm IX.
