Abstract：
The boson resonance state X is produced in company with f ₀(975)in the J/ψ hadronic decay process.If the X particle decays into a pair of pseudoscalar mesons its spin-parity is J ^pc=(odd) ^－－.The helicity formalism of angular distribution of the process has been given. How to discriminate 1 ^－－meson from 3 ^－－meson for the X particle has been discussed. We think that the X1(1573) which has been observed in the four prong channel(K ⁺K ^－π ⁺π ^－) and in company with f ₀(975)(→π ⁺π ^－)by BES collaboration may be a new resonance state.
