title: The yoneda effect in the region of ultrasoft x-ray radiation.
abstract: An experimental confirmation of the Yoneda effect in the region of ultrasoft x-ray radiation has been obtained. The angle-dependent scattering distributions from hexagonal BN at different glancing incidence angles and different wavelengths are described. The influence of surface treatment on anomalous scattering parameters is demonstrated. Some theoretical predictions are tested qualitatively.
