AN IDENTITY INVOLVING 9-j COEFFICIENTS
Keyword(s):
An identity involving 9-j coefficients which may be of some value in spectroscopic calculations is obtained. Two proofs of the identity are described. In one proof the recoupling of matrix elements of tensor operators is considered; in the other the general methods of Yutsis, Levinsonas, and Vanagas are used. Two applications of the identity to nuclear shell-model theory are described.
