| A Neutron is a [[Sub atomic particle|sub atomic particle]] with no charge and an [[Atomic weight|atomic weight]] of 1.67x10<sup>-17</sup> Kg. They are important in the nucleus as they bind to the [[Protons|protons]] by the [[Strong force|strong force]]. However free neutrons, produced in [[Nuclear fission|nuclear fission]] and [[Nuclear fusion|nuclear fusion]], are unstable and undergo [[Beta decay|Beta decay]]. Those produced in nuclear fission perpetuate the [[Nuclear chain reaction|nuclear chain reaction]]. Neutrons are [[Hadrons|hadrons]] consisting of an [[Up quark|up quark]] and two [[Down quarks|down quarks]]. It's anti-particle is the [[Antineutron|antineutron]].<sup></sup>

| '''[https://teaching.ncl.ac.uk/bms/wiki/index.php/Neutrons Neutrons]'''are perfect for studying Biological structures of different complexity. They can be used to analyse isolated [https://teaching.ncl.ac.uk/bms/wiki/index.php/Protein protein] complexes, or even [https://teaching.ncl.ac.uk/bms/wiki/index.php?title=Molecular_dynamics&action=edit&redlink=1 molecular dynamics] of whole [https://teaching.ncl.ac.uk/bms/wiki/index.php/Cell cells].<ref>J. R. Soc. Interface (2009) 6, S5674-S573</ref> The reason for wide range of possible usage for [https://teaching.ncl.ac.uk/bms/wiki/index.php/Neutrons neutrons ]is their unique properties. The similarity of wavelength to the distance between atoms gives opportunity to study the structures with atomic resolution, while the energy similarities allows study structures dynamics. Lac of charge allows deep penetration into matter, as well as does not enhance the scattering due to electron and nucleus charges. The similar scattering by light and heavy atoms and suitable magnetic moment allows magnetism studies.<ref>J. L. Baudet, (2011). Neutron Scattering.
