摘要：

We present first experimental results from evanescent neutron scattering on single crystal surfaces. The experiments have been performed at the Institut Laue Langevin on the new instrument EVA which is dedicated to surface sensitive neutron scattering work. By a careful control of both the grazing incidence angle and the grazing exit angle we were for the first time able to identify unambiguously neutron Bragg scattering which originates from the surface of the crystal. We present the experimental set-up and discuss some results which we observed from the surface of CaF2 and InP single crystals.
