Neutrons and X-rays scattering

In close collaboration with G. Fragneto (ILL, Grenoble) and J. Daillant (LIONS, CEA, Saclay) we developp both specular reflectivity and off-specular reflectivity experiments using Neutrons and X-rays to investigate physical properties of thin films at liquid/air or liquid/solid interface.
