Abstract

We report a measurement of the exclusive

e^{+} e^{-} \to D^{(*) \pm} D^{* \mp}

cross section as a function of center-of-mass energy near the

D^{(*)^{\pm}} D^{* \mp}

threshold with initial-state radiation. A partial reconstruction technique is used to increase the efficiency and to suppress background. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of

547.8 {fb}^{- 1}
