Before revision: The scattered probe is either photons ( Grazing-incidence small-angle X-ray scattering, GISAXS) or neutrons ( Grazing-incidence small-angle neutron scattering, GISANS).
After revision: The scattered probe is either photons ( grazing-incidence small-angle X-ray scattering, GISAXS) or neutrons ( grazing-incidence small-angle neutron scattering, GISANS).
