We report simultaneous measurements of neutron-capture prompt gamma emissions as well as neutron reflectivity on a polymer film with an embedded Gd layer. Enhanced -ray signals and reduced neutron reflectivity were observed when the neutron standing waves were resonantly amplified in the film. Fitting of both the -ray and reflectivity data is of significant aid in uniquely characterizing the depth profile of the polymer film as well as locating the Gd layer. © 1994 The American Physical Society.
