We propose a phase convention for the Clebsch-Gordan coefficients of S-n an
d present tables of isoscalar factors for S-3, S-4, S-5, and S-6. The isosc
alar factors have been calculated from a recursion relation due to Hamermes
h and by using symmetry properties of the Clebsch-Gordan coefficients. Appl
ications to the study of multiquark systems are discussed.
