Free-ion Energy Levels and Parameters for Pr
AbstractThis report provides a summary of theoretical and experimental studies of actinide spectra in condensed phases. Much of the work was accomplished at Argonne National Laboratory, but references to related investigations by others are included.Spectroscopic studies of the trivlent actinides are emphasized, as is the use of energy level parameters, evaluated from experimental data, to investigate systematic trends in electronic structure and other properties.Some reference is made to correlations with atomic spectra, as well as with spectra of the (II), (IV), and higher valence states.
