Neutrondiffrakciós

Neutrondiffrakciós, also known as neutron diffraction, is a powerful experimental technique used to determine the atomic and magnetic structure of materials. It utilizes the wave-like properties of neutrons to probe the arrangement of atoms within a crystal lattice. When a beam of neutrons interacts with a sample, they are scattered in specific directions, forming a diffraction pattern. This pattern is analogous to the way X-rays produce diffraction patterns, but neutrons offer distinct advantages.

Neutrons are uncharged particles, which allows them to penetrate deeply into matter, making them suitable for studying bulk materials and samples contained within other materials. Furthermore, neutrons have a magnetic moment, enabling the investigation of magnetic structures and ordering within materials. The scattering of neutrons is sensitive to the nuclei of atoms, and the intensity of the scattered neutrons at different angles provides information about the positions and types of atoms present. By analyzing the positions and intensities of the diffraction peaks, scientists can reconstruct a three-dimensional model of the material's atomic arrangement. Neutrondiffrakció is employed across various scientific disciplines, including condensed matter physics, chemistry, materials science, and even biology, for applications such as characterizing new materials, understanding phase transitions, and studying the dynamics of atoms.
