The statistical tensors of particles produced in reactions of the types a + b yields c + d and a yields c + d have been obtained in the most general case, when the incident beam and the target particles are in defimite spin states. New selection rules are deduced which supplement the previous general selection rules. The first of these rules can be regarded as a generalization of the rule according to which the polarization vector of the particles produced in the reaction is perpendicular to the plane of the reaction if the incident and target particles are unpolarized. The second rule states that the statistical tensor of a particle produced in the reaction, defined relative to the direction of its momentum, is either purely real or purely imaginary if the inci-dent and target particles are unpolarized. As a particular case, the decay of an unstable particle into particles of spins 1/2 and 0 is considered, and it is shown that the polarization and angular distribution of these particles depend only on the spin and spin state of the decaying particle.
