Résumé : A new method to deduce the neutron-electron scattering length from high-precision thermal-neutron measurements of the nuclear scattering length and of the scattering amplitudes of Bragg reflections is proposed. It consists of an extension of a Pendellösung interferometric technique proposed by Shull in 1968 to higher-order Bragg reflections in silicon. Error-bar estimates show that it could solve the ambiguity between disagreeing experimental values of the neutron-electron scattering length and provide a very precise temperature factor of silicon. © 2003 Elsevier Science B.V.
