Abstract
We report measurements of the properties of the and resonances produced in continuum annihilation near . The analysis is based on an data sample collected with the Belle detector at KEKB. We determine the masses to be and . We observe the radiative decay mode and the dipion decay mode and determine their branching fractions. No corresponding decays are observed for the state. These results are consistent with the spin-parity assignments of for the and for the .
