The antineutron is the antiparticle of the neutron with symbol n equal magnitude but opposite sign . It has the same mass as the neutron, and no net electric charge , but has opposite baryon number (+1 for neutron, −1 for the antineutron). This is because the antineutron is composed of antiquarks , while neutrons are composed of quarks . The antineutron consists of one up antiquark and two down antiquarks .
Background [ edit ]
The antineutron was discovered in proton–antiproton collisions at the Bevatron (Lawrence Berkeley National Laboratory ) by the team of Bruce Cork , Glen Lambertson, Oreste Piccioni , and William Wenzel in 1956,[2] antiproton was discovered.
Since the antineutron is electrically neutral, it cannot easily be observed directly. Instead, the products of its annihilation with ordinary matter are observed. In theory, a free antineutron should decay into an antiproton , a positron , and a neutrino in a process analogous to the beta decay of free neutrons . There are theoretical proposals of neutron–antineutron oscillations , a process that implies the violation of the baryon number conservation.[3] [4] [5]
Magnetic moment [ edit ]
The magnetic moment of the antineutron is the opposite of that of the neutron .[6] μ N μ N spin ). Here μ N nuclear magneton .
