Abstract
The cross section for e(+)e(-) --> rho pi has been measured by the BES detector at BEPC at center-of-mass energies covering a 40 MeV interva l spanning the J/psi resonance. The data are used to search for the ve ctor gluonium state hypothesized by Brodsky, Lepage, and Tuan as an ex planation of the rho pi puzzle in charmonium physics. The shape of the rho pi cross section is compatible with that of the total hadronic cr oss section. No distortions indicating the presence of a vector glueba ll are seen.
