Description
We have searched for narrow resonances in a fine energy scan of the Bhabha scattering cross section. The statistical sensitivity was 1.6% for center-of-mass energies between 1.62 and 1.74 MeV, and 0.8% between 1.74 and 1.89 MeV. We observe no significant structure and derive upper limits for the intrinsic width of resonances in the above energy range. (orig.)
