Tensorial Coupling and the Reduced Matrix Elements of One‐ and Two‐Body Operators
Jack A. Tuszyński, J.M. Dixon
Abstract The reduced matrix elements of products of tensor operators, coupled to form a non‐zero rank, are investigated to emphasize the importance of correctly incorporating all tensorial couplings. It has recently been realized that serious inaccuracies can arise, in some cases, unless the complete many body nature of the full operator and the states involved is properly incorporated. Exact results are presented for one‐ and two‐body operators which include all couplings and compare and contrast them with some approximate methods.
