For the first time, an experimental study of angular correlations has yielded a complete set of independent spin tensors of the final-state density matrix. The angular dependence of the nine spin tensors of the density matrix of the 2+ state of the 12C nucleus has been determined for the reaction l2C(a,ay4A3 )12C in the angular interval Θα (cm.) = 26-168.5° at Ea — 25 MeV. The populations of substates of this state have also been determined.
