It is argued that the ratio GAMMA((Q-barQ)'..-->..(Q-barQ)eta)/GAMMA((Q-barQ)' ..-->..(Q-barQ)..pi pi..) of hadronic transition rates between heavy quarkonium states is calculable within quantum chromodynamics in terms of triangle anaomalies in the divergence of the axial current and in the trace of the energy-momentum tensor. In the case of transitions between psi' and J/psi the present analysis is consistent with the data. More reliable test can be provided by experimental study of the transitions between UPSILON'' and UPSILON.
