Abstract
The spin-1/2 Calogero-Gaudin system and its q-deformation are exactly solve d: a complete set of commuting observables is diagonalized, and the corresp onding eigenvectors and eigenvalues are explicitly calculated. The method o f solution is purely algebraic and relies on the co-algebra symmetry of the model.
