Multilayers give rise to "Bragg" peaks in small angle X-ray and neutron scattering. The intensity of the peaks is a function of the contrast between the layers. In neutron scattering experiments, information can be obtained from change of contrast between the layers or between the interfaces and the layers. In this paper two examples are presented. In the first example, iron/ silicon multilayers are studied by polarized neutron scattering. A non-magnetic alloy is found between pure iron and pure silicon. In the second example, the modulation of hydrogen in silicon/hydrogenated silicon multilayers is shown by isotopical substitution of H, D and of HxD1-x mixtures.
