17 Neutrons and X-rays Slide: 17

18 Why use synchrotron X-rays and neutrons to study materials? They are microscopic probes which complement (or replace) other macroscopic scientific techniques Add detail on the nanometre or Å scale Tell us about structure and dynamics Slide: 18

19 Synchrotron Radiation Slide: 19

20 Synchrotron Radiation (SR) Light electromagnetic radiation produced by accelerating charged particles: electrons, positrons, protons Electrons travelling close to speed of light (Special Theory of Relativity); acceleration SR Wide band of energy/wavelength: Very intense Highly polarised from infrared (~0.1eV; ~10μm) to very hard x-ray (~1MeV; ~1fm) Slide: 20

21 Why are synchrotron x-rays useful for studying materials? Wavelength (Å) ~ interatomic spacings Diffraction atomic structures Energy (kev) >> phonon energies However, inelastic scattering dynamics Scattering power varies with atomic number Z Absorption varies strongly with energy electronic information (element specific) X-rays are electro-magnetic radiation so SR magnetic information (spin structures) Slide: 21

26 Why are neutrons useful for studying materials? Wavelength (Å) ~ interatomic spacings Diffraction atomic structures Energy (mev) ~ phonon/spin-wave energies Inelastic scattering dynamics Scattering power does not vary simply with Z Isotopes different scattering (contrast e.g H and D) Neutron spin magnetic information (structures and dynamics) Slide: 28
