Neutron Spectroscopy

Spectroscopy relies on the analysis of the resulting energy spectrum after neutrons have passed through a sample.
Thermal neutrons have wavelengths in the range of atom spacings and their energies are in the same order of magnitude as the elementary excitations. That is why neutron spectroscopy allws to study interactions of atoms in detail. For example, lattice vibrations in a crystal will lead to a energy transfer to the neutrons. Not only dynamic equilibrium properties can be detemined quantitatively, but also the change of the chemical bonding during reactions in solids can be studied by measuring the energy difference of the neutrons before and after the diffraction.
