摘要：

We report the use of deuterated polystyrene (dPS) and deuterated polyethylene (dPE) for the storage of ultracold neutrons (UCN) in an experiment to search for a finite neutron electric dipole moment (nEDM). The Fermi potential of thin film coatings on silicon was measured by cold neutron reflectometry as V(dPS) = (161 +/- 10) neV and V(dPE) = (214 +/- 10) neV. The UCN loss factor at room temperature of a dPS-coated polystyrene insulator is eta = (3 +/- 1) x 10(-4). (C) 2008 Elsevier B.V. All rights reserved.
