The experimental information indicates that for the ground pseudoscalar states, the omission of the transition amplitudes between quarkonia can result in the unreasonable result. It is believed that the mass of the pure glueball employed in the general form of the mass matrix is different from the mass predicted by lattice QCD in quenched approximation for the ground pseudoscalar glueball. The mass relation between the pure and physical ground pseudoscalar glueballs is determined from the experimental data.
