Combinatorial computation of Clebsch-Gordan coefficients

Authors


Abstract

The addition of angular momenta can be reduced to elementary coupling processes of spin-chemical structure image-particles. In this way, a method is developed which allows for a non-recursive, simultaneous computation of all Clebsch-Gordan coefficients concerning the addition of two angular momenta. The relevant equations can be interpreted easily, analogously to simple probabilistic considerations. They provide an improved understanding of the addition of angular momenta as well as a practicable evaluation of Clebsch-Gordan coefficients in an easier way than within the well-known methods.
