The dynamics of the JPC = 0-+,0++, and 2++ resonance contributions to the decay is analysed using the data obtained by BESIII collaboration. The effective coupling constants parameterising invariant amplitudes of the transitions and and masses of found from the fits are used to plot the mass spectrum of each JPC component.
