Analytical expressions for some multiplicity-free isoscalar factors of Sf⊃Sf-1
Abstract
An algebraic routine for the evaluation of analytical expressions for isoscalar factors (ISFs) of Sf⊃ Sf-1 is formulated based on the linear equation method (LEM) and the analytical continuation of the rank f. As examples, ISFs of Sf⊃Sf-1 for the coupling [f-1,1]·[f-1,1], [f-1,1]·[f-2,2], [f-2,1,1]·[f-2,1,1] are tabulated. The results demonstrate that the number of ISF tables can be greatly reduced compared with corresponding numerical results produced using other methods. © 2002 American Institute of Physics.
