Abstract: We perform a study of exclusive production of D + s D − s , D * + s D − s , and D * + s D * − s final states in initial-state-radiation events from e + e − annihilations at a center-of-mass energy near 10.58 GeV, to search for charmonium 1 −− states. The data sample corresponds to an integrated luminosity of 525     fb − 1 and was recorded by the BABAR experiment at the PEP-II storage ring. The D + s D − s , D * + s D − s , and D * + s D * − s mass spectra show evidence of the known ψ resonances. Limits are extracted for the branching ratios of the decays X ( 4260 ) → D ( * ) + s D ( * ) − s .
