Abstract：
With helicity partial wave analysis formalism, we discuss how one can distinguish f-0 resonance from f2 resonance in the process of J/ψ→fJ(θ1,1) with fJ→ππ(θ2, 2) and →K(θ3, 3) by various projections of angular distributions. We find that f-0 and f2 can give the same one-dimensional angular distributions for I(θ1)∪I(1)∪I(θ2)∪I( 2), but cannot give the same I(θ1)∪I(1)∪I(θ2)∪I(2)∪I( 3). So it is necessary to consider all three decay vertices in order to distinguish f0 from f2 by one-dimensional projections of angular distributions.
