ANGULAR-MOMENTUM PROJECTION INTEGRALS FOR COHERENT STATES

Angular momentum projection integrals arising from the coherent state representation of bosonic spectrum generating algebras are evaluated u sing analytical and algebraic methods. For the vibron model of diatomi c molecules, a closed expression is derived by direct integration. For the general case, the integral is evaluated as a 1/N expansion by exp loiting the symmetries of the underlying boson system and making use o f computer algebra.
