摘要Non-D (D) over bar decay psi(3770)->rho pi is searched for using a data sample of (17.3 +/- 0.5) pb(-1) taken at the center-of-mass energy of 3.773 GeV by the BESII detector at the BEPC. No rho pi signal is observed, and the upper limit of the cross section is measured to be sigma(e(+)e(-)->rho pi)< 6.0 pb at 90% C. L. Considering the interference between the continuum amplitude and the psi(3770) resonance amplitude, the branching fraction of psi(3770) decays to rho pi is determined to be B(psi(3770)->rho pi)is an element of(6.0x10(-6),2.4x10(-3)) at 90% C. L. This is in agreement with the prediction of the S- and D-wave mixing scheme of the charmonium states for solving the "rho pi puzzle" between J/psi and psi(2S) decays.
