Abstract
By re-identifying some of the vector meson states which have been recently observed coupling to e+e-, the authors show that in all flavour sectors the spectra of radial excitations can be well described by a Klein-Gordon-type wave equation employing a simple, linear qq potential. The wavefunctions obtained by solving the equation are coupled with quark-pair creation hypothesis to predict a number of hadronic branching ratios of the light-quark, radially excited states. The suppression of large phase-space decays of the excited states is understood.Keywords
