Rotational Small-Angle Neutron Scattering, or RSANS, is a small-angle scattering technique where a single sample is measured multiple times at different angles. That is, the sample is rotated between scans. By doing so, successive 2D slices from the 3D reciprocal-space are collected. These slices can thus be used to recover the full reciprocal-space, or a slice through this space not available in a single scan. In this sense, it is a reciprocal-space mapping method.
RSANS has been applied in a mode similar to CD-SAXS: that is, to study a nanostructured thin film, and recover the qx-qz slice of reciprocal space using a transmission-mode measurement. I.e. to measure both in-plane (qx) and out-of-plane/film-normal (qx) information. In this sense, it collects data similar to a GISAXS/GISANS experiment.
