Abstract: We perform a study of exclusive production of$D^+ sD^- s$, $D^{*+} sD^- s$,and $D^{*+} sD^{*-} s$ final states in initial-state-radiation events from $e^+e^-$ annihilations at a center-of-mass energy near 10.58 GeV, to search forcharmonium $1^{-}$ states. The data sample corresponds to an integratedluminosity of 525 $fb^{-1}$ and was recorded by the BaBar experiment at thePEP-II storage ring. The $D^+ sD^- s$, $D^{*+} sD^- s$, and $D^{*+} sD^{*-} s$mass spectra show evidence of the known $\psi$ resonances. Limits are extractedfor the branching ratios of the decays $X4260\to D^{*+} sD^{*-} s$.
