Abstract
After a review of the present state of classification in atomic spectra of lanthanides, the regular evolution of various atomic features along the sequence is traced and supplemented by new examples in the energy differences between configurations, coupling schemes, and energy parameters. This leads to the first “generalized-least-squares” study in the lanthanides, for 4ƒN6p configurations in third spectra.
