We report on an experimental study of the decays of the psi'(3684) to other charmonium states. The decays of 10/sup 6/ psi'(3684)'s were observed with the SLAC-LBL Mark II detector at the e/sup +/e storage ring SPEAR. Branching ratios have been measured for psi'(3684) decays to ..gamma.. chi where the chi decays to ..gamma..psi(3095) or to hadrons. An upper limit to 0.13% is set on the branching ratio for psi' ..-->.. ..gamma.. chi(3455) ..-->.. ..gamma gamma..psi(3095); this is a factor of 6 less than the branching ratio measured by a previous less sensitive experiment. We investigate the decay psi' ..-->.. ..gamma..eta/sub c/, eta/sub c/ ..-->.. hadrons. The decay psi' ..-->.. ..pi../sup 0/psi, which violates isospin conservation, is observed with a branching ratio of (0.15 +- 0.06)%.
