The hierarchy among the radiative gamma(pi(0), eta, eta') decay channels for the psi' looks quite different from the J/psi one. The fate of charm, namely an ultimate survival of on-shell c (c) over bar intermediate states, might give us the clue for this new puzzle in exclusive charmonium decays. A similar self-preservation has already been invoked in the past to solve the so-called rho pi puzzle. (C) 2014 The Authors. Published by Elsevier B.V.
