| Abstract: | We have searched for possible narrow resonances produced in the reaction e+e? → hadrons, at Adone, in the mass interval. 1.45–1.92 GeV. Within the present statistics, no evidence has been found. We obtain an upper limit on the energy integrated resonant cross section of about 6% of the corresponding J/ψ(3.1) value. |
