The results of a search for narrow resonances in e+e- annihilation at centre-of-mass energies between 7.23 and 10.34 GeV are presented. The experiment was performed using the MD-1 detector at the VEPP-4 storage ring. The total luminosity integral of 16 pb-1 was taken. There is no evidence that new states exist. The upper limits on the leptonic width Γee of possible resonances are less, by a factor of 10-80, than the Γee for the Υ{hooked}(1 S) meson. © 1991 Springer-Verlag.
