 This is Professor Saibal Basu from Homi Bhabha National Institute. I am proposing a course on Neutron Scattering for Condensed Matter Studies. It will cover various scattering techniques to understand structure and dynamics in condensed matter at various length and time scales. We all though express a wavelength ideally suited to decode structure, microscope specifically of materials using diffraction techniques. Neutron Scattering today is a major complementary tool for studying condensed matter. Neutrons were discovered in 1932 by Shadwick which is an important cultural of nuclear material. I have given you a brief timeline of major happenings. We all are aware about nuclear explosion in 1945 and in 1950s lots of research reactors came up including Apsara in India. We were one of the first major users of Neutron Scattering techniques. Neutrons produced in a fission have energies in the range of million electron volts. Today we also have accelerator based palatial neutron sources. There also the neutrons are produced at very high energies. The energy is brought down to million electron volt range which is equivalent to few hundreds of Kelvin temperatures using moderator materials that moderates the energy. Neutrons in this energy range are called thermal neutrons. At this energy the Broglie wavelength of neutrons is comparable to typical lattice distances and also its energy is comparable to the dynamical processes taking place in a condensed solid. Neutron incident on a crystal are diffracted in the same way as in the case of X-rays. However neutrons have certain additional advantages which needs to be pointed out. Being charged neutral neutrons penetrate deep into material unlike X-rays and they provide information from bulk. Neutron has a spin magnetic moment of minus 1.91 nuclear magneton. It is an additional degree of freedom that can be exploited to study magnetism. Neutrons are a unique tool for study of magnetism till date. Neutron is much more sensitive to lighter elements compared to X-rays. From hydrogen up to oxygen this is an advantage. Neutrons have different scattering cross sections for two isotopes in an element. Remarkably among them there is difference between hydrogen and deuterium and this contrast has been used extensively for study of organic and biological materials. The course will discuss the physics of different neutrons scattering techniques to determine the lattice structure, magnetic structure and dynamics in condensed matter. It will cover the basics of neutron scattering using Fermi Golden Rule in reasonable details. It will also discuss neutron sources and instruments used therein specifically the major reactor and spallation neutron sources. It will cover neutron scattering for structure at different length scales. This is elastic scattering of neutrons and neutron scattering for dynamics at various length scales that include molecular vibration, phonons, diffusions etc. For this course some familiarity with basic quantum mechanics, solid state physics and mathematics is expected. The scattering theory will be dealt in detail. The course targets fresh researchers and graduate students interested in characterization of their samples, the structure and dynamics in the samples using neutrons. Final master year students are also welcome. Some familiarity with extra diffraction will be a boon though not essential will attempt to explain the scattering theory from basics. Primarily researchers from physics, chemistry, material science and also some from biology will benefit from learning the technique. By the end of the course one should be able to propose experiments at one of the major neutron sources including Zruva at India and other major international sources. I welcome you all to neutrons scattering for condensed matter scattering. Thank you.
