Abstract:  

Scattering is an important phenomenon. It has deep implications nuclear and atomic physics. The scattering phenomenon can be due to electrons, X-Rays or neutrons. All the three are important and play a significant role especially in elucidating the intrinsic structure and dynamics of diverse materials.

Neutron scattering is a powerful probe used for the characterization of strongly correlated systems. Neutrons can undergo nuclear as well as magnetic scattering and hence becomes a powerful and sensitive technique for ascertaining the arrangement of specific type of atoms in a solid crystal structure.It is also sensitive to the lattice dynamics i.e., phonons.

In this seminar, I will discuss the fundamentals of neutron scattering and how neutrons can probe the structure of materials in contrast with theother available methods.
