abstract = "Angular distributions of photons with definite linear polarizations relative to the plane spanned by the momentum of initial electron and the total momentum of the V1 V 1 pair in the reaction e + e - → V → γ X (JP ) → γV 1 V 1 (V = J/ψ,ψ′,...,(1S),... and V 1 = ρ,ω,φ,...) are calculated. It is shown that the sign of asymmetry of the distributions of photons polarized in the above plane and orthogonal to it correlates with the signature P(-1)J of the X resonance with given spin-parity JP = 0±, 1±, 2± so it may help to establish this quantum number in a way which does not depend on the specific model of the X(JP ) → V 1 V 1 amplitude.",
