We report the detection and quantification of nuclear spin incoherent scattering from hydrogen occupying interstitial sites in a thin film of vanadium. The neutron wave field is enhanced in a quantum resonator with magnetically switchable iron boundaries. This approach allows the control of the wave amplitude in the layer of interest. Our results provide a pathway for the study of dynamics at surface and in ultra thin films using inelastic and/or quasielastic neutron scattering methods.
