不可约笛卡尔张量积的约化一般用3‐j张量表示。这些是第二部分中讨论的不变映射的特殊情况。A. R.库伯和R. F.斯奈德。物理学报,11,1993(1970)]。3‐j的形式主义首先是为一般群体发展起来的。然后详细讨论了旋转群的3‐j张量和旋量,给出了关于初等不变张量的一般公式。6 - j和更高的n - j符号与我们熟悉的符号一致。笛卡儿张量法与球张量法之间的相互关系贯穿始终。
The reduction of products of irreducible Cartesian tensors is formulated generally by means of 3‐j tensors. These are special cases of the invariant mappings discussed in Part II [J. A. R. Coope and R. F. Snider, J. Math. Phys. 11, 993 (1970)]. The 3‐j formalism is first developed for a general group. Then, the 3‐j tensors and spinors for the rotation group are discussed in detail, general formulas in terms of elementary invariant tensors being given. The 6‐j and higher n‐j symbols coincide with the familiar ones. Interrelations between Cartesian and spherical tensor methods are emphasized throughout.
