Introduction to Neutron Scattering - NIST
www.ncnr.nist.govIn a neutron scattering experiment a sample is placed in a beam and some of the scattered neutrons are counted. Neutron scattering experiments are designed to reveal information about the structure and dynamics of materials. Neutron diffraction yields structural information. Neutron spectroscopy yields information about dynamics.
INTRODUCTION TO NEUTRON SCATTERING - NIST
www.ncnr.nist.govWHY USE NEUTRONS?-- Neutrons interact through short-range nuclear interactions. They have no charge and are very penetrating and do not destroy samples. -- Neutron wavelengths are comparable to atomic sizes and interdistance spacings. -- Neutrons interactions with hydrogen and deuterium are widely different making the deuterium labeling method
