In this chapter, the author concentrates on the anion work, which has identified 114 bound states in the lanthanides and 41 bound states in the actinides, over half of which are new predictions. In two anions, Ce- and La-, bound opposite parity states were found, making a total of 3 [Os-]. Bound-to-bound transitions have been observed in Ce- and may have been observed in La-. The chapter discusses many properties of lanthanide and actinide atoms and positive ions. The robustness of the Relativistic Configuration Interaction (RCI) methodology lies primarily in the flexibility of basis set construction. Photodetachment spectra are an important tool in studying properties and electronic structure of negative ions. In laser photodetachment threshold (LPT) measurement, the relative photodetachment cross section of the negative ion is measured as a function of photon energy, using a continuously tunable laser beam.
