It is shown that the relativistic formulas for the angular distribution, polarization vectors and tensors of reactions of the a + b at 200 deg C an c + d type in the rest system are essentially the same as the nonrelativistic formulas if the particle spin is defined as the internal angular momentum of the particle with respect to its center of mass. The square of this intrinsic angular momentum is a Lorentz invariant. The particle spins are arbitrary, their rest masses are not equal to zero. The main difference from the nonrelativistic case is that the description of the spin state is not the same in different Lorenta systems. Therefore, for cascade reactions (such as in experiments on double scattering), corrections must be introduced in the nonrelativistic formal theory. The relativistic modifications in the angular correlations for cascades of the type pi + p at 200 deg C an Y + KY at 200 deg C an N + pi are indicated. (tr-auth)
