Abstract

We report a measurement of the exclusive e⁺e^\ensuremath-\ensuremath→D^(*)\ifmmode±\else\textpm\fiD^*\ensuremath∓ cross section as a function of center-of-mass energy near the D^(*)^\ifmmode±\else\textpm\fiD^*\ensuremath∓ 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^\ensuremath-1.
