ABSTRACT

The analysis of the Stark structure of multiplets of the ion Pr³⁺ in the Cs₂NaPrCl₆, Cs₂NaYCl₆, Cs₂NaYBr₆ crystal systems is performed in the approximation of the weak and anomalous strong configuration interaction. The calculations in the approximation of the anomalous strong configuration interaction let considerably improve the description of the Stark structure of multiplets and thus provide an opportunity to estimate covalence parameters on the basis of experimental data on the Stark structure. Covalence parameters (the parameters of distribution of electronic density) obtained this way are well conformed to the parameters calculated by means of microscopic models.
