Berrada, Y. Hassouni] Abstract.: In the framework of the U q (su(2)) quantum algebra, we investigate the entanglement properties of two-spin systems, of arbitrary spins j 1 and j 2, defined in an entanglement of deformed spin coherent states of each of the spins. We derive the amount of entanglement and we give conditions under which bipartite entangled states become maximally entangled. Using these conditions, we construct a large class of Bell states for any choices of the parameters that specify the spin coherent states.
