Abstract
Dynamic multi-coupling coefficients are introduced to describe SU(2) coupli ngs in quantum many-body systems in which the coupling coefficients of N an gular momenta are parameter-dependent. It is shown that these dynamic multi -coupling coefficients in a spin-interaction system for arbitrary spin can be determined by solving a set of nonlinear algebraic equations using an al gebraic Bethe ansatz.
