The Yoneda peak is a streak of intense scattering seen in most GISAXS experiments. It appears due to dynamical scattering; specifically, when the exit angle matches the critical angle, scattering intensity is greatly enhanced (due to, e.g., waveguide modes). It is sometimes also called the Vineyard peak.
