DEPENDENCE OF THE LINE STRENGTH OF F-F TRANSITIONS ON THE MANIFOLD ENERGY .2. ANALYSIS OF PR3+ IN KPRP4O123

To describe the experimental data of the line strength and the oscillator strength of electric dipole transition between manifolds a formula is suggested that takes into account the dependence on the energy of manifolds and the effect of electron correlation. It contains four phenomenological parameters and is applied to describe the experimental data of Pr3+ in KPrP4O12. It is shown that the dependence of the line strength on the energy of manifolds improves essentially the description of 3H4 → 3P2 transition. Copyright © 1990 WILEY‐VCH Verlag GmbH & Co. KGaA
