We calculate the width of the psi' -> h_c pi^0, which agrees with the recent BES-III data, and predict the width of the eta_c' -> chi_{c0} pi^0, \\Gamma(eta_c' -> chi_{c0} pi^0) = 1.5\\pm0.4 keV. A confirmation of this prediction would also provide additional support for a recent analysis of psi' -> J/psi pi^0 (eta), where loops are claimed to play a prominent role.","authors_text":"Christoph Hanhart, Feng-Kun Guo, Gang Li, Qiang Zhao, Ulf-G.
