    "abstract": "The aim of this article is to present the interference effects which occur\nduring the time evolution of simple angular wave packets (WP) which can be\nassociated to a diatomic rigid molecule (heteronuclear) or to a quantum rigid\nbody with axial symmetry like a molecule or a nucleus. The time evolution is\nunderstood entirely within the frame of fractional revivals discovered by\nAverbukh and Perelman since the energy spectrum is exactly quadratic. Our\nobjectives are to study how these interference effects differ when there is a\nchange of the initial WP. For this purpose we introduce a two parameter set of\nangular momentum coherent states. From one hand this set emerge quite naturally\nfrom the three dimensional coherent states of the harmonic oscillator, from\nanother hand this set is shown to be buit from intelligent spin states.We have\nalso compared our coherent states to some previously constructed using boson\nrepresentation of angular momentum. The time evolution of coherent states for\nsymmetric top is also discussed.",
