__________________________________________________________ AMR ATTIA AMR ATTIA __________________________________________________________________________ 2n summer school in DUBNA. slide 3 June 4, 2010 What's the Neutron diffraction ? Neutron diffraction is a method by which neutrons are used to determine the atomic and/or magnetic structure of a material. It can be equally well applied to study crystalline solid, gasses, liquids or amorphous materials
