Interprétation des Configurations 4fN5d et 4fN6s par la Méthode Paramétrique Généralisée

摘要: The interpretation of the configurations 4fN6s and 4fN5d has been improved by using complete matrices for N = 6 8. Generalized constants which describe evolution electrostatic parameters as a function have fitted least-squares method, from 492 energy levels second spectra, 498 third spectra 143 fourth spectra. A few revisions earlier classifications are reported together with some new predicted evaluations in Tm IV Er IV.
