Ii. Guseinov et al., COMPUTATION OF CLEBSCH-GORDAN AND GAUNT COEFFICIENTS USING BINOMIAL COEFFICIENTS, Journal of computational physics, 122(2), 1995, pp. 343-347
Using binomial coefficients the Clebsch-Gordan and Gaunt coefficients
were calculated for extremely large quantum numbers. The main advantag
e of this approach is directly calculating these coefficients, instead
of using recursion relations. Accuracy of the results is quite high f
or quantum numbers l(1) and l(2) up to 100. Despite direct calculation
, the CPU times are found comparable with those given in the related l
iterature. (C) 1995 Academic Press, Inc.
