Abstract: The results of a search for narrow resonances ine<superscript>+</superscript>e<superscript>−</superscript> 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<superscript>−1</superscript> was taken. There is no evidence that new states exist. The upper limits on the leptonic widthΓ<subscript>ee</subscript> of possible resonances are less, by a factor of 10–80, than theΓ<subscript>ee</subscript> for the ϒ(1S) meson.
