Introduction and Review of Previous Literature,lts. In order to achieve this goal it is necessary to review material which many readers may have been exposed to elsewhere. This review is rather brief, and the bibliography (sect. 1.4) includes references to specific sections of textbooks, monographs, or papers where the material is discussed in mantiandrogen 发表于 2025-3-29 12:59:30

Numerical Example: 4FJ States of Nd3+ (4f3), assume that the levels are pure .F.. We assume that L, S, and J are all good quantum numbers; then we consider matrix elements of H. in equation (9.9) with J’ = J and L’ = L. Thus,.. The values of the reduced matrix elements <J | U.| J> <ℓ . C..ℓ> for the .F state of Nd. are as in table 11.1. In obARK 发表于 2025-3-30 08:08:13
