Abstract
We report the creation of a confined slow beam of heavy-water molecules with a translational temperature around . This is achieved by filtering slow from a thermal ensemble with inhomogeneous static electric fields exploiting the quadratic Stark shift of . All previous demonstrations of electric-field manipulation of cold dipolar molecules rely on a predominantly linear Stark shift. Further, on the basis of elementary molecular properties and our filtering technique we argue that our beam contains molecules in only a few rovibrational states.
