antineutrons
Neutrons' opposite counterparts
Antineutrons are the antimatter counterparts of neutrons.
Like neutrons, they have no electric charge, but their internal composition differs—made of antiquarks rather than quarks.
When an antineutron meets a neutron, they annihilate each other, releasing energy.
Antineutrons appear in particle physics experiments and cosmic ray interactions.
