report on photo association experiments with sodium atoms from a Bose-Einstein condensate. A photoassociation laser beam of appropriate frequency hits the Bose-Einstein condensate and forms excited molecular states with a lifetime of about 10 ns. The production of molecules is detected as a loss in atom number of the BEC. We present preliminary data where we studied the width of the molecular transition, and the rate at which molecules are formed. We observe a laser power dependent red shift of the molecular transition frequency.
