Introduction and Review of Previous Literature,ore detail. Unfortunately, as in most fields of science, a number of different notations (in various alphabets) are used in the literature; it is hoped that this review will help overcome some of this difficulty.脆弱带来 发表于 2025-3-23 22:03:13
Numerical Example: 4FJ States of Nd3+ (4f3),taining these values we have used Nielson and Koster’s results (1963) in equations (9.9) and (9.10) for the reduced matrix elements, (LS|U.|LS), for L = 3 and S = 3/2; the Racah coefficients (6-j symbols) are found in Rotenberg et al (1969).aerial 发表于 2025-3-24 00:14:15
Point-Charge Model Developed at HDL,, and the A. were calculated using the point charges at the valence values for the constituent ions. These calculations generally gave the twofold field 10 times too large, the fourfold fields approximately in good agreement, and the sixfold fields 10 times too small.thrombus 发表于 2025-3-24 03:19:30

Earth System Monitoring, Introduction,ecifically, Judd suggested that such terms would arise if one of the electrons in the configuration nℓ. polarized a nearby ion, and the remaining N — 1 electrons interacted with the induced multipolar moments. The investigation of this interaction was performed later (Morrison, 1980), assuming only a dipole polarizability.anachronistic 发表于 2025-3-24 15:55:21

,Free-Ion Hamiltonian Unfilled Configuration nℓN , not be familiar with these assumptions and may not remember many of the concepts and most of the technical jargon used in the field of atomic spectra, we review some of these briefly. We stick strictly to those concepts which apply to transition-metal ions and rare-earth ions.
