NEU Theory


« Back to Glossary Index

In Neu Theory, an acronym for “neutron equivalent unit.” A neu is an absolute system of measurement by which a specific physical value is compared to the neutron physical quantity set at unity. Examples:

  • mass: the measured 1.674 929 351 x 10-27 kg mass of the neutron is set equal to one atomic mass unit or a neumass of 1.000000.
  • magnetism: the measured -0.966 236 47 x 10-26 J T-1 magnetic dipole of the neutron is set equal to -1.000 magneton.

The neu values of atomic nuclei are provided in the Neumass & Charge Radius Table.
