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.
