Neutronspektroskopialla, or neutron spectroscopy, is a scientific technique used to study the structure and dynamics of materials. It employs neutrons as probes, exploiting their wave-like and particle-like properties. Neutrons are particularly useful because they are uncharged, allowing them to penetrate deeply into matter without significant interaction with atomic electrons. This unique characteristic enables the investigation of atomic nuclei and the vibrations within crystal lattices.

The fundamental principle behind neutron spectroscopy involves scattering neutrons off a sample. The energy and momentum of the scattered neutrons are then measured. By analyzing the changes in these properties, researchers can deduce information about the sample's atomic and magnetic structure, as well as its collective excitations, such as phonons (vibrations) and magnons (magnetic excitations). Different types of neutron scattering experiments exist, including elastic scattering for structural analysis and inelastic scattering for studying dynamics.

Neutron spectroscopy finds applications across various scientific disciplines. In condensed matter physics, it is used to understand magnetic ordering, superconductivity, and phase transitions. Materials science utilizes it for characterizing the properties of alloys, polymers, and composites. In chemistry, it helps in studying molecular vibrations and hydrogen bonding. Biology also benefits from this technique for investigating the structure and dynamics of biomolecules. The ability to probe light elements like hydrogen and lithium, which are often difficult to study with other methods, makes neutron spectroscopy a powerful tool.
