Generalized spin-statistic selection rules (SSSR) for the arbitrary number of photons Nγ involved in atomic transitions are established. These selection rules are similar to those for systems of many equivalent electrons in atomic theory. The latter are a direct consequence of symmetrization postulate (SP) and the Pauli exclusion principle (PEP) (or its more general formulation is spin-statistics connection (SSC)). In this sense, the SSSR play the role of the exclusion principle for photons: they forbid some particular states for the photon systems. This selection rule represents an extension of the Landau-Yang theorem (LYT) to the photons involved in atomic transitions. The possible experimental test of generalized SSSR are also proposed.
