Comparison to other techniques<strong>Inelastic</strong> Neutron <strong>Sc<strong>at</strong>tering</strong>• Low energy probe ( i = 25 meV)• Better energy resolution• Couples only to nuclei and spins• Not sensitive to charge excit<strong>at</strong>ions(e.g. plasmons)• Large samples required<strong>Inelastic</strong> Electron <strong>Sc<strong>at</strong>tering</strong>• Can focus beam ~ 1Å• Decent energy resolution (0.5 eV)• Sample damage• Multiple sc<strong>at</strong>tering• Does not work in H 0• Requires UHVLight (Raman) <strong>Sc<strong>at</strong>tering</strong>• q=0 probe• Super high energy resolution (0.1 meV)• Super high flux (10 22 photons/sec on sample)• Polariz<strong>at</strong>ion selection rules• cheap
